Abstract

By modifying existing methods for synthesizing polyaniline, a polyaniline polymer having a new constellation of material properties has been produced. The material properties of the polymeric compositions disclosed herein enhance the use of polyanilines in a wide variety of processes that use such materials, for example processes used in the formation of filtration membranes.
