Abstract

Vanadium pentoxide (V₂O₅) film has thermal sensitive, gas sensitive, electrochromic and thermochromic. It is a common and easy to process material. The thin film samples of vanadium oxide were prepared by sol-gel method in this paper. The flocculation precipitation in the precursor is amorphous V₂O₅, which has no effect on the film thickness after filtration. The surface defects of the film were reduced by means of lamination and spin coating. The relationship between the flatness of vanadium oxide and the improvement of electrochromic performance is analyzed. The cyclic stability of vanadium pentoxide films was improved by 10% using polymer tetrabutylammonium perchlorate as supporting electrolyte. Tetrabutylammonium tribromide only increases the cyclic stability of the films by 2.3% due to the instability of the Br^-.
