Abstract
The electropolymerization of aniline on polyurethane film-coated platinum electrodes (PU/Pt) in electrolyte solutions with pH = 1 – 13.7 yields polyaniline that is conducting and bears a structure similar to conducting polyaniline prepared in aqueous acid solutions as indicated by FT-i.r. spectra and optical absorption investigations. It is found that aniline is electropolymerized mainly at the polyurethane-platinum interface, which is strongly acidic even in a basic electrolyte solution due to the strong limitation of the polyurethane layer of the PU/Pt electrode on the diffusion of H + released during the reaction and OH − in the bulk electrolyte solution through the polyurethane layer. A mechanism for the electrodeposition of aniline on PU/Pt electrodes is suggested.
