Graphical abstract Highlights • Novel VO x -based films coated with SiO 2 superhydrophobic coating are prepared. • VO x /SiO 2 composite films have good thermochromic and self-cleaning properties. • SiO 2 superhydrophobic coating render VO x -based films self-cleaning property. • The original excellent thermochromic of VO x -based films have been retained. Abstract The practical application of VO 2 smart glass is usually restricted by poor thermochromic property and contaminant. In this study, the VO x /SiO 2 composite films were fabricated using magnetron sputtering and sol-gel preparations. Compared with VO x -based films, the VO x /SiO 2 composite films showed the superhydrophobic property, and its water contact angle was up to 165°. At the same time, the VO x /SiO 2 composite films retained the original excellent thermochromic property with solar regulation of 13.95%, luminous transmittance of 37.34% and the low phase transition temperature around 38℃. This study provided guidance for the combined application of VO 2 smart glass and superhydrophobic coating. [ABSTRACT FROM AUTHOR]
