ELECTRONICALLY CONDUCTING POLYPYRROLE AND CO-POLYMERS OF PYRROLE,COMPOSITIONS CONTAINING THEM,METHODS FOR MAKING THEM,AND ELECTROCHEMICAL CELLS USING THEM

摘要

Electronically conducting compositions comprising electropolymerised polypyrrole or copolymers of a pyrrole are described. These compositions may be either porous or non-porous materials in the form of films, powders, dendriform materials, or various shapes formed as desired by pressing powders of the compositions of the invention. The electronically conducting compositions of the invention can be prepared by several processes which are described, and a preferred process involves a multi-phase system, and more preferably, a two-phase system, one phase being aqueous. These compositions are stable over a range of chemical and electrochemical conditions and are useful in a number of applications, including electrodes for electrochemical cells such as electrochemical energy storage cells.
