Influence of disordered morphology on electrochromic stability of WO3/PPy

Mechanism: A schematic of the mechanism is proposed in above fig. The mechanism is based on three step process: (i) WO3 coated on ITO by electrodeposition followed by thermal treatment. It produces ordered nanoarrayed morphology. (ii) A second step involving deposition of PPy by chemical bath deposition on ITO. It possesses globular morphology. (iii) When PPy coated on WO3, PPy applies shearing force on WO3 and produces disordered nanoarrayed morphology.339
