Silicones are perhaps the most misunderstood and least understood class of commercial polymeric material. They are used in multiple everyday applications, but their chemistry is generally neglected and often not taught in chemistry, polymer science and materials science curricula. But for some reason, however, many people who have been trained in these disciplines know what PDMS is - or think that they do. In this talk, silicones will be overviewed, several examples of recently completed research will be described and on-going research directions will be discussed. The preparation of Extremely Crosslinked Poly(dimethylsiloxane) (PDMS), Low Hysteresis Hydrophobic Silicone Surfaces, and a Self Healing Silicone Polymer will be described as well as a few other topics.
Thomas J. McCarthy received his B.S. in Chemistry from the University of Massachusetts in 1978 and his Ph.D. in Organic Chemistry from the Massachusetts Institute of Technology in 1982. Since then he has been a faculty member in the Polymer Science and Engineering Department at the University of Massachusetts, Amherst, serving as Head from 2000-2003. His research has involved various aspects of polymer surface and interface science, metal and metal oxide surface chemistry, wetting physics, covalently attached monolayers, polymer adsorption, thin films, supercritical fluids and ionic liquids. His current research is directed at developing silicone chemistries and materials in several directions and using wetting and dewetting strategies to prepare structured composite materials. He has advised over 80 Ph.D. students and postdoctoral scholars
