“Nanogel Star Polymers: Synthesis, Characterization and Applications”
IBM Almaden Research Center
Nanogel stars are star polymers where the arms emanate from a functionalized, crosslinked polymer core. They are prepared in a versatile one-step procedure from preformed functionalized arms and a bifunctional core-forming material using organic catalysis. The arms of the star can be homopolymers, random copolymers, or block copolymers. Depending on the application, the materials can be amphiphilic materials which require no micellar assembly. The nanostructures themselves can be water insoluble, biocompatible, or biodegradable. The amphiphilic materials can load cargos either by encapsulation or by covalent bonds to the polymer functionality. The polymeric stars are deformable to accommodate both hydrophilic and hydrophobic surfaces or to promote aggregation in polar solutions. The functionalized stars can be assembled in a layer-by-layer fashion using hydrogen bonding, electrostatic, ligand exchange, or ligand-metal interactions to produce layered structures . I will discuss the synthesis, characterization, and potential applications of these versatile materials.
Robert D. Miller received his PhD in Organic Chemistry from Cornell University and spent a postdoctoral year at Union Carbide Research Institute. He then joined IBM at the T.J. Watson Research Laboratories in Yorktown Heights NY, and moved to the San Jose Research laboratory in 1972. After a series of research and management positions, he is currently a Principal Research Staff Member. His research activities have included basic photochemical processes and mechanisms, radiation sensitive polymers and microlithography, synthetic methods utilizing multifunctional synthons, synthetic applications of strained ring materials, spectroscopy and chemistry of reactive intermediates, new polymeric materials for nonlinear optics, polymeric light emitting diodes, novel polymeric architectures, silicon and germanium containing polymers, controlled polymerization techniques, functionalized organic and inorganic nanoparticles, materials for molecular and organic electronics, organic materials for magnetic storage, polymeric electronic materials for semiconductor applications, nanoporous thin films, photovoltaic materials and structures, sublithographic self assembly using block copolymers, air bridge dielectrics, radiation definable dielectrics, solution and CVD precursors for low-k applications, and others. He is a member of the American Chemical Society and the Materials Research Society, and currently serves on the editorial advisory boards of Chemical Reviews and Advanced Functional Materials. Dr Miller is a Fellow of the Division of Polymeric Materials Science, the Materials Research Society, and the American Chemical Society. He is a member of the National Academy of Engineering and is the recipient of the 2010 American Chemical Society award for Chemistry of Materials. Dr. Miller is a co-inventor on more than 150 patents and has published more than 380 articles in refereed technical journals.
