Abstract:

This presentation is aimed at demonstrating the progress with the high-temperature synthesis and characterization of new inorganic nano-tubes (INT) and fullerene-like (IF) nano-particles (NP) from 2-D layered compounds. Two important categories of new IF/INT nanostructures will be discussed in particular: 1. Synthesis of Doped IF/INT of WS2 (MoS2) by rhenium and niobium; 2. Synthesis of IF and in particular INT from the ternary misfit compounds, like PbS-TaS2, GdS-CrS2 and many others. The synthesis of 1-D nanostructures (nano-tubes) from this vast group of layered materials is particularly promising. Major progress has been achieved in elucidating the structure of INT and IF using advanced microscopy techniques, like aberration corrected TEM and electron tomography. Recent optical, electrical and mechanical measurements with WS2 nano-tubes will be briefly discussed. Re-doped IF-MoS2 NP exhibit superior solid lubrication behavior in different environments and can find numerous applications in e.g. medical technology, which will be briefly demonstrated. Applications of the IF/INT as superior solid lubricants and for reinforcement of polymer, as well as other nano-composites, which gained a lot of momentum in recent times, will be briefly discussed. Few recent studies indicate that this brand of nano-particles is non-toxic and biocompatible. With expanding product lines, manufacturing and sales, this generation of superior lubricants is becoming gradually a commodity.

Abstract:

Novel nanomaterials such as polyimides (PIs), polyamides (PAs), conjugated polymers and polynorbornenes (PNBs) were successfully prepared from various polymerization techniques including low temperature polycondensation, Suzuki coupling and ring-opening metathesis polymerization (ROMP). PIs derived from different architecture designs revealed unique physical-mechanical, electrical and chemical properties. In addition, the PIs films also exhibited high thermal stability (Tg >300oC), transparency above 90% in visible light region (400-700 nm) and flexibility which are important for optoelectronic applications. PAs with the pyridine moiety displayed good film forming abilities, flexibility, high thermal resistance and yellow emission at 552 nm due to excimer generated by protonation. Conjugated polymers were used for single-walled carbon nanotube (SWCNT) wrapping to separate metallic and semiconducting nanotubes. Their chiralities such as (6,5), (9,5) or (8,7) were identified by photoluminescence-excitation (PLE) maps as well as UV/vis/NIR absorption spectra. Polytriarylamines- or poly(triarylamine-fluorene)-based conjugated polymers with water/alcohol solubility were applied for the hole-transporting materials of solar cells including perovskite solar cells and organic photovoltaics (OPVs). The conjugated polymers and PNBs containing hexa-peri-hexabenzocoronene (nanographene) were well dispersed in cyclohexylpyrrolidone (CHP) by bath sonication and possessed exfoliation emission in PLE maps. PNBs synthesized via ROMP showed excellent transparency (90%) and high thermal stability (Tgs >160oC). Triarylamine-containing polymers had electrochromic properties and capacity for multiple colour change reversibilities. The triphenylamine-alt-fluorene conjugated copolymer with hexaphenylbenzene (HPB) and pyrene as asymmetrical pendant groups showed the strong near-infrared (NIR) electrochromic absorbance attributed to intervalence charge transfer by the incorporation of the HPB moiety. These polymeric materials had high organo-solubility in common solvents and as a result can be used for solar cells, organic field effect transistors, polymer memories, and smart windows applications.
