Researchers at the Univ. of California at Los Angeles have developed the first solid-state process for synthesizing poly(3,4-ethylenedioxythiophene), or PEDOT, reports Fred Wudl, professor of chemistry and materials. PEDOT is one of the most successful conducting polymers used in industry.
Current processes for making conducting polymers suffer from the fact that it is not possible to obtain well-defined, highly ordered polymer structures in the presence of the necessary catalysts or initiators, Wudl points out. For example, PEDOT is produced by chemical or electrochemical oxidation of monomer solutions, which results in defect sites and a relatively low degree of intermolecular …
