Functionalized polyurethane and meniscus prosthesis, the preparation method thereof and the uses therefor

A functionalized polyurethane, characterized in that it comprises a self-healing polyurethane elastomer and an adamantane-hyaluronic acid composite, wherein the adamantane-hyaluronic acid composite is coated on the surface of the self-healing polyurethane elastomer, and the thickness of the adamantane-hyaluronic acid composite is 10-20 μm;

• the self-healing polyurethane elastomer is made from raw materials in the following parts by weight:
• 1-2 parts of hard segment raw material,
• 4.5-9 parts of soft segment raw material,
• 0.262-0.522 parts of dimethylglyoxime,
• 0.412-0.824 parts of chain extender,
• 0.04-0.08 parts of crosslinking agent;
• the adamantane-hyaluronic acid composite is made from raw materials in the following parts by weight:
• 10-20 parts of hyaluronic acid,
• 2.3-4.6 parts of diepoxy compound,
• 0.5-5 parts of adamantane.
