โœฆ Synopsis

Electrochemical synthesis of polyaniline was carried out in aqueous sulfuric acid solutions of aniline on porous pand n-silicon under galvanostatic, potentiostatic and potential pulse regimes. It is shown that the introduction of catalytic quantities of oxidants, potassium hexachloroiridate, potassium dichromate, potassium permanganate and chloranilic acid, in electrolytes accelerates the formation of polymer films and lowers the overvoltage of electrosynthesis. The resulting polymer coatings are characterized by cyclic voltammetry and IR spectroscopy. It is shown that polyaniline coatings on porous pand n-silicon electrodes are electroactive and conducting in anodic and cathodic ranges.

Using a vacuum CVD technique, alumina films were deposited on 10 lm diameter carbon fibers, and 120 lm diameter silicon carbide fibers. This was accomplished by exposing resistively heated microfiber substrates to a sublimate of [Al(O-t Bu) 3 ] 2 , while the reaction chamber was maintained at 120 C
