Electrical Conductivity of Modified Poly-Acetylenes and Polypyrroles

Abstract

A partial stabilization of the conductivity of undoped polyacetylene has been reached by chemical modifications. No stabilizing effect was obtained, however, in the iodine doped state. The influence of various comonomers and counterions on the conductivity of polypyrrole and its stability to air is reported. By a treatment of polypyrrole with alkalines and acids a chemical shifting of the conductivity and an improvement of the stability has been achieved.
