Our group is interested in advanced high performance polymer nanocomposites: the processing, characterization and prediction of properties. ●These materials are often used in extreme environments such as conditions found in rocket ablatives and fire. Materials comprised of polymer and nanoparticles offer improvement over traditional composites in mechanical, barrier and thermal properties while maintaining specific gravity and optical clarity. To achieve this level of performance, one must achieve high levels of dispersion and good interfacial compatibility. Current research focuses on formation of novel morphologies/networks which lead to optimized barrier layers and to toughness. ●Another thrust is to utilize dispersion to form nanochannels in hydrogels used in medical diagnostics. These nanocomposite hydrogels alter the mobility of proteins under electrophoretic flow, and may alter electro-osmosis significantly. A combined theoretical and experimental approach will inform us better how this new important class of materials is a barrier to transport and/or produces important separations of native proteins. Conversely, these studies will illuminate the conditions under which nanoparticles can be electrophoretically self-assembled. ●A third area of research is to understand environmental fate and transformation of metal nanoparticles such as gold or silver in surface waters. Our early understanding for gold nanoparticles is that they interact with humic acids in such a way to facilitate transport and promote dispersion stability when disposed of into a watershed. We are currently working on a project involving ultrafiltration nanocomposite membranes evaluating performance improvement in the membrane, e.g. higher fluxes.
