US 12,234,310 B2 · Blood-compatible fluorine-based polymer and thin film comprising same

Abstract

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.
