Physical Chemistry

My group focuses on the use of solution casting, spin-coating, self-assembly, and the Langmuir-Blodgett (LB) technique to explore the physical chemical aspects of polymer dynamics in confined geometries and at surfaces and interfaces. These systems are ideal for studying contemporary issues affecting nanotechnology like nanofiller reinforcement in polyhedral oligomeric silsesquioxane (POSS)/polymer nanocomposites, magnetic nanoparticle-lipid interactions for drug delivery systems, and biomimetic engineering of cellulose/polymer interfaces in composites. Characterization of these phenomena is accomplished through neutron scattering and X-ray reflectivity at the National Institute of Standards and Technology (NIST), and dynamic mechanical and thermal analysis (DMTA), rheology, differential scanning calorimetry (DSC), surface light scattering (SLS), the fluorescence recovery after photobleaching (FRAP) technique, ellipsometry, x-ray photoelectron spectroscopy (XPS), surface plasmon resonance (SPR) and optical (OM), fluorescence (FM), atomic force (AFM), scanning electron (SEM), transmission electron (TEM), and Brewster angle (BAM) microscopy at Virginia Tech.
