Abstract

Silver films (∼10−6m) have been electrodeposited within a polymer matrix (∼10−5 m) of polyvinylidene fluoride trifluoroethylene copolymer 60-40 cast on the surface of a stainless steel electrode. It is shown that the fractal geometry of the polymer-metal interface, which is not open to direct observation, can be characterized by means of ac impedance measurements made on the electrode in acetonitrile solution.
