Abstract

Tungsten oxide coatings are chemically vapor deposited on polycarbonate via aerosol assisted at 125°C. The effect of the Ar:O ₂ ratio on the structural, morphological and electrochemical properties of the samples is investigated. The coating grown using Ar:O ₂ ratio of 50:50, exhibits the best electrochemical activity and the fastest colouration-bleaching response. At the same time it offers a high specific capacitance that does not degrade upon at least 1000 successive charging-discharging cycles as studied by voltammetry in a solution of 1 M LiClO ₄. The importance of morphology towards the enhancement of the electrochromic behaviour of the coatings is discussed.
