Preliminary studies for obtaining polyaniline on nickel electrode [articol]

Abstract

In our studies the possibility of obtaining polyaniline films on the nickel electrode through electrodeposition was investigated. The method used was cyclic voltammetry. The working electrode (anode) was glossy nickel. The electrolyte solution was diluted sulfuric acid with or without aniline. The experiments were performed at temperatures ranging from 25 to 45oC and an electrochemical potential interval between – 0.5 ÷ 1.6 V. A white green to blue color (depending on the electrochemical potential) polyaniline film was deposited on the nickel electrode. The main reactions that take place on the electrode and the effect of the working conditions on these processes were identified through cyclic voltammetry.
