A PHOTOELECTRON SPECTROSCOPIC INVESTIGATION OF CONDUCTING POLYPYRROLE-POLYAMIDE COMPOSITE FILM

X-ray photoelectron spectrum of the electrochemically prepared polypyr role and polypyrrole-polyamide composite films exhibit an additional s trong high binding energy peak at 402.0 eV corresponding to N+ moietie s. Intensity of this peak is significantly reduced upon electrochemica l reduction. Atomic concentrations derived from the observed N+ and F (stemming from the dopant BF4-) peaks reveal a slightly higher cation/ anion ratio for this composite and suggest that the composite has a di fferent chemical composition than the corresponding polymers.
