Abstract

Abstract The amine salts of linear polyaniline compounds, including substituted polyaniline compounds, are useful, semiconductors. These materials are generally soluble in popular organic solvents and have resistivities between 10 - 3 and 10 9 ohm-cm. These compounds are useful in the formation of semiconductor compositions, including self-supporting films, and various semiconductor elements such as antistatic films and fibers.
