Electrical Properties of Pyrrole and its Copolymers.

Abstract

Electrochemically prepared polypyrrole film have metallic conductivities in the range 40-100/Scm whereas poly-N-methyl pyrrole films have conductivities more typical of a semiconductor approx. .001/Scm. Films made by the electrochemical polymerization of mixtures of pyrrole and N-methylpyrrole have redox potentials intermediate between those of either monomer indicating that they are in fact random copolymers. The electrical conductivity and thermopower measured as a function of copolymer composition show no evidence for an abrupt metal-semiconductor transition. All these polymers are stable in air to temperatures in excess of 100 C. (Author)
