Abstract
Indium tin oxide (ITO) electrode was modified with anilino-methyl-triethoxysilane (AMTS), and then the polyaniline film covalently bonded to ITO electrode (PANI-ITO) was prepared by the chemical oxidation polymerization. The adhesive strength of PANI film on ITO electrode was tested by sonication. It was found that PANI-ITO exhibited a much better stability than that on bare one. Cyclic voltammetry (CV) and UV–vis spectroscopy measurements indicated that the oxidative potentials of PANI-ITO decreased and the film exhibited high electrochemical activities and lithium storage capacity. Moreover, the coloration time was 2.1 s, while the bleaching time was 1.0 s. It can be found that PANI-ITO exhibits the better electrochromic properties.
