The invention relates to the technical fields of production and preparation of inorganic functional materials, and in particular relates to a preparation method of a temperature-sensitive VO2 photocurable flexible film. The method comprises the steps of performing coating directly by using a resin dispersion liquid in which doped vanadium dioxide is added, and performing UV photocuring to obtain the temperature-sensitive VO2 photocurable flexible film, wherein the doped vanadium dioxide is vanadium dioxide powder doped with at least one selected from a W atom, a Mg atom, a Mo atom, a Sb atom,a Ti atom, a Zr atom and a Fe atom. The preparation method provided by the invention has a simple process, the resin solution is used as a substrate, the doped vanadium dioxide is added, so that the prepared VO2 photocurable film has good transparency and high flexibility; and in the prepared temperature-sensitive VO2 photocurable flexible film, a phase transition temperature range of VO2 powder is from 20 to 60 DEG C, th
