Plasma Enrichment of Electrochemical Properties of Conductive Polymers

The polyaniline and polyaniline with carbon were treated in low temperature plasma process. Two steps treatment was applied, i.e. first with Ar and then with CO2 reactive gas in a new plasma device with rotary chamber. Textural properties of the polymers were characterized using low temperature isotherms of N2. Electrochemical properties of the polymers were carried out using galvanostatic studies, cycling voltammetry and electrochemical impedance spectroscopy. The physicochemical and electrochemical measurements have confirmed that capacitance properties are connected with a plasma exposition. Plasma modification process has visible influence on the changes in polymers porosity. The moderate increase of capacitance of the modified polymers has been also observed.
