AN ELLIPSOMETKIC STUDY OF POLYAN1LJNE FILMS GROWTH

The film growth of poliyaniline in perchloric, suilfuric and hydrochloric acid aqueous electrolyte are studied with ellipsometry. The growth rate and morphology of the deposited films of polyaniline depends on the anions in the electrolyte. The film deposited in perchloric acid aqueous solution is compact. In sulfuric or hydrochloric acid aqueous solutions the film initially is compact but subsequently deposited layers have porous, stucture.     

THE PROGRESS OF SPECTROELLTPSOMETRIC INVESTIGATION FOR ANALYZING ELECTROCHEMICAL REACTIONS

This paper describes the initial idea of building up a new approach of spectroscopic ellipsometry for studying electrochemieal reaction from some of the author's experimental results on ellipsometry.
