A new composite material prepared by mixing polycarbonate with carbon black has been tested as new kind of cathode. This material has been compared with a conducting polymer precipitated onto polycarbonate, both in aqueous and organic solutions. We report some examples of electrodeposition of magnetic alloys (Lanthanides/Transition metals) in Formamide. In this medium, the use of thin polypyrrole films cathodes had remained impossible. The preparation of amorphous and magnetic alloys onto PC/carbon black is evidenced by RBS.

En préparant un composite conducteur polycarbonate/noir de carbone, nous avons obtenu un nouveau matériau susceptible d'être utilisé comme cathode pour la préparation électrolytique de recouvrements métalliques. Ces cathodes sont comparées à des cathodes de Ppy déposé sur polycarbonate. Nous décrivons ici la réalisation d'alliages magnétiques en couches minces. Ces alliages Lanthanides/Métaux de transition sont préparés en milieu organique (Formamide : FA) où les cathodes constituées de films minces de polypyrrole conducteur ne sont plus utilisables. Le caractère métallique et amorphe de ces alliages est démontré par analyse RBS.

Key words: conducting polymer -- electrodeposotion -- magnetic alloy
