CURRENT FLOW SUPPRESSION BY POLYPHENYLENE-OXIDE ELECTRO-POLYMER FILM FORMATION

This paper examines the phenomena of current flow suppression that can be observed when platinum is anodically polarised in solutions of phe nol and several of its derivatives. The formation of polymer films is examined with respect to the mechanism of current flow suppression. Th e techniques involved in this study are primarily electrochemical in n ature, such as potentiodynamic sweeping and a.c. impedance spectroscop y. The results lead to some unusual conclusions, in that for a number of examples the polymer film resistance does not appear to dominate th e resistive response.
