Fluorine-based composite polymer film and preparation method thereof

Abstract

The present invention relates to a composition for forming a composite polymer film, a method for preparing the composition for forming a composite polymer film, a composite polymer film and a method for preparing the composite polymer film. The composition for forming a composite polymer film comprises: a fluorine-based polymer solution comprising a fluorine-based polymer; and polyvinylidene fluoride nanoparticles dispersed in the fluorine-based polymer solution. The method for preparing the composition for forming a composite polymer film comprises the steps of: preparing a fluorine-based polymer solution comprising a fluorine-based polymer; and dispersing polyvinylidene fluoride nanoparticles in the fluorine-based polymer solution. The composite polymer film comprises: a polymer matrix formed from a fluorine-based polymer; and polyvinylidene fluoride nanoparticles dispersed in the polymer matrix. The method for preparing the composite polymer film comprises the steps of: preparing a fluorine-based polymer solution comprising a fluorine-based polymer; preparing a composition, for forming a composite polymer film, by dispersing polyvinylidene fluoride nanoparticles in the fluorine-based polymer solution; and forming the composite polymer film by applying the composition for forming a composite polymer film.
