Abstract

We report the synthesis and characterization of a series of polyanilines (PANI) that are templated with a polymer acid at varying molecular weights. The polymer acid template of choice, poly(2-acrylamido-2-methyl-1-propanesulfonic acid), or PAAMPSA, was synthesized via conventional free-radical polymerization with molecular weights ranging from 45 kg mol^-1 to 724 kg mol ^-1. Subsequent aniline polymerization in the presence of PAAMPSA yielded water-dispersible, conductive PANI-PAAMPSA. The electrical conductivity of PANI-PAAMPSA increases by approximately three-fold with decreasing PAAMPSA molecular weight. This trend is accompanied by significant structural changes, including increases in PANI crystallinity and conjugation length. These conductivities (0.4-1.1 S cm^-1) exceed the highest reported for polymer acid-doped PANI systems.
