The invention discloses a preparation method of a stretchable flexible electrochromic film, and belongs to the technical field of fine chemical engineering and material science. Mixing electrolyte, color-changing dye, organic monomer and solvent, adding initiator, stirring and forming film to obtain the stretchable flexible electrochromic film; the organic monomer comprises one or more of acrylamide, N-hydroxymethyl acrylamide, hydroxyethyl acrylate, hydroxypropyl acrylate, methyl acrylate ethyl acrylate, butyl acrylate, isooctyl acrylate, N-methylene bisacrylamide and polyethylene glycol diacrylate. The color-changing film prepared by the method has the characteristics of high electric response speed, high color contrast and the like, and also has good tensile recovery, the tensile strain can reach 500%, the tensile recovery rate is 98.0%, and the diversified requirements of people on wearable electronic products can be met. |
