More Information
Summary:The invention discloses a modified collagen with 5-30% collagen, 50-90% poly-3-hydrobutanoate-3-hydrovalerate and 5-20% partial amidifying polyacrylamide and making method and application, which comprises the following steps: adopting PHBV as basic material to make PHBV film; irradiating through ultraviolet; grafting polyacrylamide; making amidified PHBV to do Hofmann decomposing reaction; producing amidifying PHBV; bonding PHBV and collagen with excellent compatibility and dynamics.
