摘要：

Two procedures were examined for the fabrication of poly(chlorotrifluoroethylene)/precious metal composite electrodes in an attempt to reduce the size of the active sites on the surface. A grinding procedure used with graphite was unsuccessful with platinum in that individual platinum particles became isolated from one another. As a result, the electrode material was nonconducting. A procedure which involved sputter coating the poly(chlorotrifluoroethylene) with gold prior to compression molding was successful. Electrodes fabricated with this procedure had active areas less than about 1% of their geometric area and behaved as an array of isolated ultramicroelectrodes at times less than 0.1 s.
