Abstract
In an aspect of the present invention, a fluoropolymer represented by 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 the fluoropolymer is coated on glass, the surface energy can be lowered to 19 mN/m or less and the light transmittance can be increased by 2% or more. At the same time, it has the effect of exhibiting excellent pencil hardness. In addition, the fluoropolymer provided in one aspect of the present invention can be applied as a surface coating and membrane material of various products due to its high solubility in general organic solvents, despite having very low surface energy during coating. Furthermore, the fluoropolymer has excellent adhesive power to the substrate surface and is capable of hardening, so it can be applied to various fields such as automotive glass, building exterior materials, condensers in fresh water or power plants, and solar cells.
