摘要: Provided are an anticoagulation and anticalcification biological material and a preparation method therefor. The preparation method includes the following steps: introducing, on a biological tissue, a polymerizable reactive group, and undergoing free radical copolymerization with a zwitterion. In the present invention, by introducing a reactive group capable of free radical polymerization to a biological tissue and undergoing free radical copolymerization with a zwitterionic monomer, collagen in the biological tissue is crosslinked at multiple sites by means of a polymer, thereby achieving sufficient crosslinking within and between collagen fibers, improving the stability of the biological tissue, and prolonging the service life of the biological tissue. Moreover, a zwitterion is introduced to the surface of the biological tissue, to improve the anticoagulation performance, promote the in-situ endothelialization of a biological valve, and prevent the calcium element deposition.
