Disclosed is a blood-compatible polymer represented by Formula 1. A polymer obtained by grafting a fluorinated methacrylate onto a polyvinylidene fluoride copolymer and provided in one aspect of the present invention is a polymer with blood compatibility, and may provide a blood-compatible material with hydrophobicity. In addition, it is possible to provide a material with controlled contact angle and surface energy properties by controlling the hydrogen fluoride length of the fluorinated methacrylate monomer for modification. Furthermore, it is possible to provide coating with controlled surface properties and blood compatibility through a simple process. Furthermore, it is possible to provide a freestanding polymer film with blood compatibility.

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.
