Abstract
An original method of growing a new class of thin films of composite conducting materials is described. A technological approach which allows the deposition of a fluorinated polymer-polypyrrole alloy on a solid substrate is outlined. This procedure employs a cosputtered granular metal in which the metal grains are chlorinated to produce an oxidizing agent capable of promoting pyrrole polymerization. Morphological, optical and electrical characterization of the material are reported. The low-temperature behaviour of the resistance was investigated. The polymer blend seems to be less disordered than polypyrrole thin films grown on an oxidizing salt pattern from the vapour phase.
