Phosphorylcholine-containing high-strength polyurethane hydrogel and preparation method thereof

The invention relates to a phosphorylcholine-containing high-strength polyurethane hydrogel and a preparation method thereof, and the hydrogel is prepared from a double-bond-terminated polyurethane segmented copolymer, 2-methacryloyloxyethyl phosphorylcholine and an alkene copolymerization monomer through free radical copolymerization. The hydrogel is prepared by dissolving the double-bond-terminated polyurethane segmented copolymer, 2-methacryloyloxyethyl phosphorylcholine, the alkene copolymerization monomer and an initiator in a solvent, and performing ultraviolet-initiated free radical polymerization reaction at room temperature. The preparation method is simple, the raw material source is wide, and the prepared hydrogel is good in biocompatibility, also possesses extremely strong compression resistance and tensile resistance, can be used as a tissue engineering restoration skeleton material and the like, and possesses obvious application prospect in the field of biomedical materials.
