  • SUPERHYDROPHOBIC AND SELF-CLEANING RADIATIVE COOLING FILM AND PREPARATION METHOD THEREOF
    Publication number: 20210054185
    Abstract: Disclosed are a superhydrophobic and self-cleaning radiative cooling film and a preparation method thereof. The preparation method includes the following steps: 1) dissolving P (VDFx-HFPy) and PDMS in a composite polar solvent to obtain a translucent composite polymer solution of P (VDFx-HFPy)/PDMS; 2) adding a non-solvent dropwise to the obtained solution to allow for a phase separation of P (VDFx-HFPy)/PDMS to form a sol; 3) casting the sol; drying the cast sol to obtain a film are porous inside with micro/nano rough structures of low surface-energy on the surface. The preparation method of the present invention is simple, and can be used for large-scale production.
