Polyaniline: Synthesis, Chemistry and Processing

The polyanilines and their derivatives are a large class of mixed oxidation state polymers which can be synthesized by the oxidative polymerization of the appropriate monomeric aniline. Certain oxidation states of the polymer can be doped to the metallic conducting regime either by aqueous protonic acids or by partial oxidation. The synthesis and key chemical reactions of the intrinsic properties of the doped polymer by stretch-orientation which results in significant increases in conductivity, crystallinity and tensile strength will be described.
