NOVELTY - Preparing dual-drive type super-hydrophilic photothermal film comprises (i) placing the film-forming material in an oven to heat, mixing with an organic solvent, stirring and dissolving, allowing to stand and defoaming to obtain spinning solution, and using electrostatic spinning method to prepare the nanofiber spinning base film; (ii) mixing the photo-thermal conversion material, super-hydrophilic modifying agent and deionized water, and ultrasonically processing to obtain uniform dispersion, filtering the dispersion by a vacuum filtration process, depositing the photothermal conversion material and super hydrophilic modifying agent on the surface of the nanofiber spinning base film, drying, calcining and cross-linking to obtain super-hydrophilic photo-thermal conversion nanofiber film; and (iii) performing primary heat pressing the super-hydrophilic photo-thermal conversion nanofiber film to improve integrity, folding, and performing secondary heat-pressing and shaping. USE - The method is useful for preparing dual-drive type super-hydrophilic photothermal film. ADVANTAGE - The film provides by not limited by the natural condition and the weather condition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for dual-drive type super-hydrophilic photothermal film prepared by above method.
