Title:
FLUOROPOLYMER, FLUOROPOLYMER COMPOSITION CONTAINING SAME, AND FLUOROPOLYMER FILM USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/132415
Kind Code:
A1
Abstract:
In one aspect of the present invention, a fluoropolymer represented by chemical formula 1 is provided. The fluoropolymer provided in one aspect of the present invention can obtain low surface energy and high light transmittance, and thus can be applied to various applications requiring such properties. In particular, when coated on glass, the surface energy can be lowered to 19 mN/m or less and the light transmittance can be increased by at least 2%. At the same time, the fluoropolymer has an effect of exhibiting excellent pencil hardness. In addition, the fluoropolymer provided in one aspect of the present invention can be used as a surface coating material and a membrane material for various products due to high solubility in common organic solvents, despite having a very low surface energy during coating. Furthermore, the fluoropolymer has excellent adhesion to the surface of a base material and can be subjected to a curing process, and thus, the fluoropolymer is applicable to various applications such as automobile glass, building exterior material, condensers in power plants, fresh water, and solar batteries, etc.
