Préparation et caractérisation d’un matériau d’électrode à base d’un semiconducteur modifié par un film de polymère fonctionnalisé et contenant des particules métalliques

Abstract

The objective of this work is the elaboration and the characterization of the composite materials Silicon/Polypyrrole-Copper thin films for electronic organic and photovoltaic applications.The polymer film is obtained by electrochemical oxidation of the monomer (pyrrole) in an organic medium.The electrodeposition of copper was initially studied on silicon in order to determine the experimental conditions. The incorporation of copper in polypyrrole films was made by immersion the modified electrode in a solution composed of it salt, follow-up of an electroreduction in an aqueous solution to precipitate Cu+2 ions in the shapes of metal particles in polymer films.
