Experimental study of aniline deposition as semiconducting polymer

Polyaniline films, with electric properties in their oxidized form has been obtained by electrochemical and chemical methods. The electrochemical growth may be characterized as autocatalitic mechanism. The layer thickness is correlated with the number of the cycles in the deposition process. Chemical deposition yield to a blue thin polymer layer as nonconducting form, the conducting form being obtained by soaking in H₂SO₄0.1 M; 24 hours. The absorption properties in the visible-ultraviolet wavelength range of the chemical deposited layers have been investigated
