Intelligent packaging opens a new development direction in printing and packaging industry, and realizes efficient information interaction between packaging and consumers. The research and development of intelligent packaging materials is the basis of intelligent packaging technology with different functions. Vanadium dioxide (VO2) is one of the main materials of thermochromic film, which is widely used in the field of intelligent thermal insulation and temperature control materials. Among various crystal structures of VO2, the M phase with semiconductor characteristics can change into metal R phase reversibly at 68 ℃, which can block the solar infrared band to achieve the purpose of active temperature control. The methods of controlling the phase transition temperature and optical properties of VO2 thermochromic films are reviewed. Based on the research of layered structure, the performance of VO2 film is improved by doping elements, compounding different materials and modifying the surface of film, enabling this kind of intelligent packaging material to control the ambient temperature of products effectively. Therefore, it is more suitable for use in daily life and provides guarantee for product quality. Meanwhile, the application trend of VO2 thin films is prospected.
