Highly Selective Ionic Block Copolymer Membranes

Abstract

The objectives of this project were to (1) develop a fundamental understanding for selectivity criteria in selective membranes and to (2) develop new highly selective membranes. The first objective focused on investigating multicomponent transport phenomena in ionic polymer membranes on a molecular scale using time-resolved Fourier transform infrared-attenuated total reflectance (FTIR-ATR) spectroscopy. The outcomes of this research project provided a fundamental understanding of multicomponent transport mechanisms and provided a new body of knowledge in selective barrier materials. The second objective focused on developing new membranes based on ionic block copolymers with improved selectivity. We were successful in accomplishing these goals and the attached report highlight the key results from this project.
