Abstract

Electrochemical polymerization without a supporting electrolyte would most probably yield a material with more reproducible and better difined propertis, and is therefore a technique to be encouraged. The formation of an electroactive, self-doped polymer (see Figure) by electropolymerization is described and the analysis of the resulting films presented.
