摘要：

In this study pyrrole was electropolymerized into polymers having three types of morphology. In the first case, convoluted tubes and dendrites were deposited on filled polymeric and roughened electrodes. Secondly, free-standing fractals were formed, radiating from central anodes. In some instances the polymers were grown across filter papers located at the base of the anode and at the surface of the solvent. In the third instance, high surface area fibrillar forms were obtained by in-situ polymerization within coated, gamma-alumina isoporous membrane hosts, followed by leaching in alkali. In all cases the morphology of these products is described by optical and scanning electron microscopy.
