Abstract
Polyaniline salts of toluenesulfonate (TS) and sulfonated poly( p-vinylphenol) (SPVP) have been prepared. The polyaniline salt of TS exhibited a room-temperature electrical conductivity of 10 S cm −1. The activation energy for electrical conduction was 0.02 eV, which was significantly smaller than the value 0.04 eV reported for other salts. The aromatic nature of the organic anion is expected to enhance the interchain diffusion of charge carriers. The electrical conductivity of the polyaniline salt of the polymer anion was of the order of 10 −4 S cm −1. A polyaniline base derived from the SPVP salt was water-soluble in the presence of excess NaSPVP, due to complexation between the two polymers.
