The objective of this study is to investigate optical and electrochemical characteristics of Polyaniline (PANI)/indium tin oxide/glass (ITO/Glass) by cyclic voltammetry and potentiostatic method. The electrochromic behaviors of the PANI/ITO/Glass were performed in 0.1 M lithium perchlorate (LiClO4)/propylene carbonate (PC) electrolyte. The coloration efficiency (η) of the PANI/ITO/Glass was 9.35 cm2/C. Furthermore, the experimental results observed that the color of PANI/ITO/Glass was changed from Green to Light Green.
