Study on electrochemical properties of polyaniline thin film on aluminium substrate

Abstract

Electrosynthesis of polyaniline (PANi) on aluminiumsubstrate at an current constant of 1.75 mA/cm² in solution of anilin 0.3 M and H2SO4 1 M was the aim of this paper. The electrochemical properties of PANi thin film decided their working ability and lifetime in electrochemical cell. The results showed this thin film was electrochemically increased with cyclic voltammetry number because of its electron transfer resistance were decreased from 11.23 kΏ to 5.93 kΏ
