Polymer blends, composites and nanocomposites
Inorganic-organic hybrid composites
Inorganic-organic hybrid composites with ordered and disordered nanostructures were synthesized via sol-gel reaction utilizing an amphiphilic polyethylene-block-poly(ethylene oxide) diblock copolymer as the directing agent.
Dispersion and assembly of carbon nanotubes in epoxy resinsIt remains a major challenge to disperse carbon nanotubes (CNTs) in a polymer matrix to obtain polymer/CNT composites with maximum material performance. We study dispersion and assembly of CNTs in epoxy resins. In particular, we have achieved an extremely superior dispersion of multiwalled carbon nanotubes (MWCNTs) in epoxy matrix, and the resultant CNT/epoxy composites exhibit significantly improved mechanical properties.
Blending different polymers is an extremely attractive and cost-effective way of obtaining new materials from existing commercial polymers. Our previous work involved many aspects of polymer blends, from fundamentals such as specific interactions, miscibility, phase behavior and structure to material properties and performance.
Our research is focused on the time-dependent morphological and rheological changes that accompany the preparation of polymer blends. In particular, we have examined the morphological and rheological evolution associated with the in situ polymerization of phenoxy/SAN blends. The rheological property changes are closely related to morphology development and mechanisms of phase separation induced during in situ polymerization. The results provide a clear picture of how the blends develop, as well as a direct correlation between the changes in rheological behaviour and morphology. This research plays an important role in developing multicomponent designer plastics as commercially attractive materials.
