“Selective Cleavage of Amphiphilic Block Copolymers: Synthetic Methods for Preparation, and Applications as Thin Films”

PLEASE NOTE: Location is once again at the Hilton Garden Inn in San Mateo this month

Abstract

Block copolymers are well-known to develop ordered morphologies as a result of the non-favorable interactions between the two segments. The morphology that is developed is a consequence of the relative volume fraction between the domains, and is on the size scale of the tens of nanometers. This length scale is desirable for many applications in nanotechnology. In order to elaborate on block copolymers as a scaffold it is necessary to first develop ordered arrays of block copolymers. Once ordered, the remaining challenges are the selective removal of one of the two domains to create a nanoporous template followed by the selective back filling of the open spaces. This presentation will describe two synthetic strategies to prepare well-defined block copolymers with a cleavable junction point between the two segments. The demonstration of the stimuli responsiveness of these block copolymer will also be highlighted for preparing nano-sized arrays of silica, gold wires, and iron oxide toroids.

Speaker Background

E. Bryan Coughlin studied chemistry at Grinnell College, and received is B. A. in 1988. Upon the completion of his Doctorate in Chemistry at the California Institute of Technology in 1993, he joined the Central Research and Development Department of the DuPont Company. He was on the technical staff for nearly six years. He is a co-inventor of the DuPont's Versipol® Polyolefin Technology Platform, and has over 25 patents to his name. Since 1999 Dr. Coughlin has been on the Faculty of the Polymer Science and Engineering Department at the University of Massachusetts, Amherst where he is currently a Full Professor. His research interests are broad and cover aspects of synthetic polymer chemistry and material characterization studies of polymers for use in fuel cells, lithium ion batteries, light harvesting polymer for organic photovoltaics, functional hybrid materials, and fire-safe polymers.
