The development and the study of both ionic and electronically conducting polymers have been. in the past few years. areas of· increasing interest. These new materials are. in fact. being considered for many technological applications. namely low weight. high energy density batteries and sensors. This volume contains the proceedings of a workshop on this subject. sponsored by the U.S. Army Research. Development and Standardization Group (U.K.). which took place in Sintra - Portugal from July 27 to July 31. 1986. The workshop. which included lectures. communications and discussion panels. was very sucessfull and the combination of ionic with electronically conducting polymers and their applications. not usually together in workshops or conferences. proved to be an excellent idea. Lisbon December. 1986 Luis Alcacer ix THE ELECTROCHEMISTRY OF ELECTRONICALLY CONDUCTING POLYMERS J. O'M. Bockris and David Miller Department of Chemistry Texas A&M University College Station, Texas 77843 USA ABSTRACT. The new field of the electrochemistry of electronically conducting polymers is reviewed. A brief historical account traces the beginning of organic electrodes to Ka11mann and Pope, who, in 1960, observed charge injection and conductance in anthracene electrodes.
