Abstract

Vanadium pentoxide films have been synthesized by ultrasonic spraying using self-fabricated equipment. Experimental condition is easy to control without the presence of high temperature, electric field, and vacuum. The substrate on which the film deposits does not require high conductivity and the obtained film is good in uniformity. The method is especially effective to process large area films. In this study, the obtained films were investigated for their structural, surface morphological, electrochemical and optical properties. Compared with electrodeposited vanadium pentoxide films, sprayed ones exhibit relatively poor charge storage capacity, but a similar transmittance value. Under comprehensive consideration, the ultrasonic spraying method is preponderant choice for preparing large area films for electrochromic devices.
