Use of ZnO as antireflective, protective, antibacterial, and biocompatible multifunction nanolayer of thermochromic VO2 nanofilm for intelligent windows

- A multifunctional VO2/ZnO bilayer film is designed and deposited by magnetron sputtering apparatus.
- The ZnO top layer can enhance the antireflective, antioxidative and anti-corrosion functions of the VO2 film.
- The ZnO top layer can endow VO2 film with excellent antibacterial performance.
- The ZnO top layer can attenuate the cytotoxicity of VO2 thin film.
