Abstract :

The electrochromic properties of organo-inorganic hybrids of WO3/PPy thin films have been synthesized with a twostep process successfully. The WO3 layer was prepared by electrodeposition technique on conducting glass substrate (indium doped tin oxide-ITO) followed by thermal treatment and polypyrrole thin films were deposited using chemical bath deposition (CBD) technique. The structural, morphological, optical and electrochromic responses of WO3, PPy and WO3/ PPy films are described. To study the electrochromic (EC) properties of the as deposited films, cyclic voltammogram (CV), chronoamperometry (CA), chronocoulometry (CC) and optical modulation were performed. The kinetic investigation (response time) and coloration efficiency were found to be enhanced appreciably. The WO3/PPy shows improved EC performance than their solitary act.
