Polymers of Intrinsic Microporosity (PIMs): High Free Volume Polymers for Membrane Applications

Abstract

We are developing new types of polymer - termed polymers of intrinsic microporosity (PIMs) - which in the solid state behave like molecular sieves. As pervaporation membranes, they show selectivity for organics over water. As gas separation membranes, they exhibit a remarkable combination of high permeability and good selectivity for gas pairs such as O2/N2.
