Ion Conduction in Polymerized Ionic Liquid Thin Films

ORAL

Abstract

The ion conductivity in thin films is typically assumed to be isotropic. We have developed methods to measure in-plane and through-plane ionic conductivity in thin homopolymer and block copolymers. Specifically, we are studying the conductivity in imidazolium-containing polymerized ionic liquids as a function of film thickness. These data will be compared to conductivity measurements in a triblock copolymer with a polymerized ionic liquid midblock.
