The essence of Materials Chemistry can be observed in various fields i.e., organic, inorganic, analytical and physical and biomimetic studies. Organic chemistry provides organic polymers for use in structures, films, fibres, coatings, and so on. It provides materials with complex functionality, a bridge between materials science and medicine and provides a sophisticated synthetic entry into nanomaterial. Inorganic chemistry deals with the structure, properties, and reactions of molecules that do not contain carbon, such as metals. It helps us to understand the behaviour and the characteristics of inorganic materials which can be altered, separated, or used in products, such as ceramics and superconductors. Analytical chemistry determines the structure, composition, and nature of substances, by identifying and analysing their various elements or compounds. It also gives idea about relationships and interactions between the parts of compounds. It has a wide range of applications, like food safety, Nano biopharmaceuticals, and pollution control. The basic characteristics of how matter behaves on a molecular and atomic level and how chemical reactions occur are physical chemistry. Based on the inferences, new theories are developed, such as how complex structures are formed and develop potential uses for new materials correlating materials chemistry. In biomimetic study, the structure and function of biological systems were taken as models and employed in the design and engineering of materials.

Materials science and pharmaceutical chemistry are disciplines at the intersection of chemistry, especially synthetic organic chemistry, and pharmacology and various other biological specialties, where they are involved with design, electrochemical synthesis and development for market of pharmaceutical agents, or bio-active molecules (drugs).

Compounds used as medicines are most often organic compounds, which are often divided into the classes of small organic molecules (e.g., atorvastatin) and "biologics" (erythropoietin, insulin), the latter of which are most often medicinal preparations of proteins (natural and recombinant antibodies, hormones, etc.). Inorganic and organic compounds are also useful as drugs (e.g., lithium and platinum-based agents such as lithium carbonate and cis-platin.

Identification of new drugs, often called "hits", which are typically found by assay of compounds for a desired biological activity. Further synthesis of the formulations needs the analysis of SAR for the desired mechanism of action. If not chemical alterations of excipients in formulations can be done for better effects. Biomaterials are used to treat joint replacements, heart valves, breast implants.

Certain principles are there to synthesize a novel material : to develop an understanding of different materials systems, to know the origins of physical, chemical, and functional properties of different materials, to study basic principles of synthesis and characterization of materials, to understand the origins of functional responses of materials and also the role of materials in science, industry, and technology. Often a pure substance needs to be isolated from a mixture or after chemical reactions (which often give mixtures of chemical substances). From ores, extraction can be done by means of oxidation catalysis and reduction whereas in laboratory by techniques like Hydraulic Washing, Magnetic Separation, Froth Floatation Method, Leaching and so on.

Biomaterials are any matter, surface, or construct either from nature or synthesized in the laboratory and that interacts with biological systems. A ceramic is a non-metallic material composed of inorganic molecules, generally prepared by heating a powder or slurry and glassy materials are hard, brittle, and not crystalline which results in optical transparency. Solid state chemistry, also sometimes referred to as materials chemistry is the study of the synthesis, structure, and properties of solid phase materials, particularly, but not exclusively of, non-molecular solids. Thus it has a strong overlap with solid-state physics, mineralogy, crystallography, ceramics, metallurgy, thermodynamics, materials science and electronics with a focus on the synthesis of novel materials and their characterization. Mixtures of metallic materials are called alloys, are more commonly used than the pure metal. By alloying, some of the key properties of metals can be altered. Composite materials are mixtures of two or more bonded materials. The design and synthesis of these materials with different approaches can be done here.

Light harvesting is the study of materials and molecules that capture photons of solar light. This includes studies to better understand the light-harvesting properties of photosynthetic organisms. Examples are chlorophylls and carotenoids in plants and man-made solar cells, optical materials and so on. The robust nature of chemical energy storage is embodied in the millennia between the photosynthesis of prehistoric plants, which stored the energy of the sun, and the recovery and combustion of the resulting fossil fuels today, which releases that energy. The challenge for the future is to capture, store, and release energy on an immediate timescale and in a sustainable way. Hence chemical reactions should be controlled for future purpose. Gases and liquids are fluids for us whereas designer fluids are tailored in such a way that these are altered and used in various processes like adsorption and so on for an efficient and clean future energy. This process is also widely applied in case of biochemistry, geochemistry.

Fuel cells, photovoltaic, composites are a few examples of devices and structures in which functionality is achieved by deliberately juxtaposing disparate types of materials, and where the processes that are fundamental to the device performance occur at the interfaces between constituents. The long-term stability of the interfaces between electrodes and separator membranes is essential for sustaining the electrochemical methods responsible for the generation or storage of electric energy in fuel cells or batteries. The key to producing materials systems with the desired performance characteristics is the ability to fabricate them consistently and with Nano scale precision to design specifications. Certain strongly correlated materials are used in case of superconductors in which the behaviour of electrons cannot be described. The density functional approach excels where dynamical correlations are modest in size, which is in the weakly correlated materials. Hence electronic structures should be controlled. By completely performing the solution analysis, one can use it in an effective way analysis for novel and safe ingredients of preparations.

Magnetically tunable photonic structures are prepared in alkanol solutions by using silica-modified super paramagnetic Fe₃O₄ colloids as building blocks. Repulsive electrostatic and magnetically induced attractive forces contribute to the ordering of the Fe₃O₄ @ SiO₂ colloids. The ability to form tunable photonic structures in non-aqueous solutions allows the fabrication of field-responsive polymer composite materials films for potential applications as displays and sensors. Metal-organic frameworks (MOFs) are materials in which metal – to-organic ligand interactions yield porous coordination networks with record-setting surface areas surpassing activated carbons and zeolites. They are used in the storage and separations of gases, catalysis and others. There are two major methods to construct DNA Nano structures, the tile-based and DNA origami methods. The tile-based approach is an ancient method that provides a good tool to construct small and simple structures, usually with multiple repeated domains. In contrast, the origami method, at present, would appear to be more appropriate for the construction of bigger, more sophisticated and defined structures which facilitate molecular modelling.

In the past decade, lithium-ion (Li-ion) batteries have been considered as one of the viable alternative technologies for applications such as electrical vehicles and grid energy storage for renewable energies (e.g., solar and wind) due to their high energy density and long cycle life. Recent nanotechnology leads to the development of advanced electrode materials for high-performance Li-ion batteries. The recent advances are in graphene-based composites and their application as cathode materials for Li-ion batteries. They focus on the synthetic methods of graphene-based composites and their superior electrochemical performance in Li-ion batteries.  Advances in oxide semiconductor materials and devices continue to fuel leading edge developments in display technology, and transparent electronics. Nano crystalline oxide semiconductor offers a host of advantages such as low cost and high scalability. In semiconductor device applications, oxide semiconductors stem from a number of attributes primarily their ease of processing, and high field effect mobility, rising in stackable process nature on silicon circuits. Carbon nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure. These carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. Owing to their extraordinary thermal conductivity and mechanical and electrical technologies, carbon nanotubes act as additives to various structural materials.

Polymer chemistry is a multidisciplinary science that deals with the chemical synthesis and chemical properties of polymers which were considered as macromolecules. Polymers describe the bulk properties of polymer materials and belong to the field of polymer physics as a subfield of physics. Polymers are of two types-natural ( e.g., rubber, amber ), synthetic ( e.g., polyethylene, nylon, PVC ). Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network. General methods of synthesis include-Biological synthesis and  also by modification of natural polymers. Laboratory research is generally divided into two categories, step-growth polymerization and chain-growth polymerization. Polymers are characterized by the presence of monomer units and microstructures and they can be determined by means of many lab techniques. Surface functionalization of a polymer structure is the key component of a coating formulation allowing control over such properties as dispersion, film formation temperature, and the coating rheology. The association of other additives, such as thickeners with adsorbed polymer material give rise to complex rheological behaviour and excellent control over a coating's flow properties.

Polymer blends are members of a class of materials analogous to metal alloys, in which at least two polymers are blended together to create a new material with different physical properties. A polymer alloy includes multiphase copolymers but excludes incompatible polymer blends. These materials combine high modulus, heat resistance and impact strength in addition to flame retardant. Polymer processing is done by extrusion and injection moulding; other processes include calendering, compression. Polymer testing capabilities include advanced trace chemical analysis, diverse analytical capabilities and identification of chemicals composition, unknown materials and chemical contamination. It is used to identify fundamental structural information including molecular weight, molecular weight distribution and information on branching. Polymers are manufactured under pressured conditions, pressureless conditions and so on.

The effects of ultrasound induce certain physical changes like the dispersal of fillers and other components into base polymers (as in the formulation of paints), the encapsulation of inorganic supplements with polymers, changing of particle size in polymer powders, and most important is the welding and cutting of thermoplastics. In contrast, chemical changes can also be created during ultrasonic irradiation as a result of cavitation, and these effects have been used to favour many areas of polymer chemistry. In materials science, the sol-gel conversion is a method for producing solid materials from small molecules. This method is used for the fabrication of metal oxides particularly the oxides of silicon and titanium. The process involves conversion of monomers into a colloidal solution (sol) that acts as the precursor for an integrated network (or gel) of either discrete particles or network polymers. Important precursors are metal alkoxides. Polymers produced under sonication had narrower poly dispersities but higher molecular weights than those produced under normal conditions. The fastness of the polymerization was caused by more efficient dispersion of the catalyst throughout the monomer, leading to a more homogeneous reaction and hence a lower distribution of chain lengths. The electrical and magnetic phenomena alter the properties of materials for better prospective in manufacturing. Plastic fabrication is the design, manufacture and assembly of plastic products through one of a number of methods.

Nanostructures deal with objects and structures that are in the 1—100 nm range.  In many materials, atoms or molecules cluster together to form objects at the nanoscale. This leads to interesting electromagnetic, optical and mechanical properties. The term 'nanostructure' is often used when referring to magnetic technology. Microstructure is defined as the structure of a prepared surface or thin foil of material as revealed by a microscope above 25× magnification. It deals with objects from 100 nm to a few cm. Most of the traditional materials (such as metals and ceramics) are micro structured. Macrostructure is the appearance of a material in the scale millimetres to meters—it is the structure of the material as seen with the naked eye. Atomic structure deals with the atoms of the materials and how they are arranged to give structure of molecules, crystalline solids etc., The length scales involved are in angstroms (0.1 nm). The way in which the atoms and molecules are bonded and arranged is fundamental to studying the properties and behaviour of any material. Crystallography is the science that examines the arrangement of atoms in crystalline solids. Crystallography is very much useful for materials scientists. Polymers display varying degrees of crystallinity and many are completely non-crystalline. Glass, some ceramics, and many natural materials are amorphous, not possessing any long-range order in their atomic nuclei.

Surface science is the study of physical and chemical phenomena that occur at the interface of two phases along with solid–liquid interfaces, solid–gas interfaces, solid–vacuum interfaces, and liquid–gas interfaces. It is closely related to study of surface, which targets at modifying the chemical composition of a surface by incorporation of selected elements or functional groups that produce various desired effects or improvements in the properties of the surface or interface.  Biomedical materials are prepared from tissue engineering for the compatibility in the human body. Optoelectronics is the study and application of electronic devices that source, detect and control light, usually considered as a sub-field of photonics. These devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation. It is based on the quantum mechanical effects of light on electronic materials, especially semiconductors, occasionally in the presence of electric fields. Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature. Superconducting materials are some of the most powerful electromagnets known. They are used in MRI/NMR machines, mass spectrometers, and beam-steering magnets used in particle accelerators. Molecular electronics is the study and application of molecular building blocks for the fabrication of electronic materials.

Two-dimensional (2D) materials have attracted much attention in the past decade. They have high specific surface area and also electronic engineering and properties that differ from their bulk counterparts due to the low dimensionality. Graphene is the best known and the most studied 2D material, but metal oxides and hydroxides (including clays), dichalcogenides, boron nitride (BN), and other materials that are one or several atoms thick are receiving increasing attention. They exhibit a combination of properties that cannot be provided by other materials. Many two-dimensional materials are synthesized by selective extraction process which is critically important when the bonds between the building blocks of the material are too strong (e.g., in carbides) to be broken mechanically in order to form Nano structures. These have a thickness of a few nanometres or less. Electrons are free to move in the two-dimensional plane, but their restricted motion in the third direction is governed by quantum mechanics. Magnetic topological insulator comprised of two-dimensional (2-D) materials has a potential of providing many interests  and applications by manipulating the surfaces states like yielding quantum anomalous Hall effect giving rise to dissipation-less chiral edge current, giving axion electromagnetism and others. The chemistry of electrical, optical, thermal and mechanical properties varies in a peculiar style and these materials are applied widely in case of ambipolar electronics, transistors and so on.
