Abstract: | The stability of C60 and palladium two-component films, C60/Pd, has been investigated. The effect of different polymerization conditions on the electrochemical stability of the film
upon prolonged potential cycling has been studied. Stable voltammetric behavior was observed for polymers formed at potentials
less negative than the potential of third C60 reduction step. The incorporation of palladium particles into the structure of C60/Pd polymers increases the polymer stability. The C60/Pd films are doped with supporting electrolyte cations during reduction. The size of these cations is a crucial factor in
determining the stability of the film. A strong solvent effect on the potential stability of the film was also observed. The
wildest range of stable voltammetric properties was found for acetonitrile and N,N-dimethylformamide. No effect of the temperature on the film stability was observed. The results reported in this work allow
for the determination of the optimal conditions for the formation of stable C60/Pd films. |
