摘要：

The electrochemical properties of mouldable graphite-epoxy composite electrodes have been studied as a function of graphite content. The shape of ferri-ferrocyanide voltammograms relates to the ratio of graphite and an adsorption process. The dielectric constant from spectroelectrochemical impedance measurement of this composite electrode is maximum when the proportion of graphite is ca. 60 wt%. An electrochemical equivalent circuit is proposed. The graphite-epoxy composite acts as a multi-microelectrode near this proportion.
