ELECTRODEPOSITION OF POLYANILINE FILMS ON POROUS P-SILICON AND N-SILICON

Polyaniline is synthesized electrochemically on p-Si and n-Si from aqu eous solutions of sulfuric acid in galvanostatic, potentiostatic, and potentiopulsed modes. It is shown that introducing K2IrCl6 into electr olyte as a catalyst accelerates formation of the polymer film and lowe rs the electrosynthesis voltage. Cyclic voltammetry of polymer coating s thus manufactured is conducted and their IR spectra are obtained. Po lyaniline films on the p-Si and rt-Si electrodes are electroactive and conduct in anodic and cathodic directions.
