The invention provides a surface-physically modified polyarylether bone implantation material containing a phthalazinone structure and a preparation method of the material. Phthalazinone polyarylethernitrile of which the surface is provided with a bone-formation active coating prepares a functional coating on the surface of phthalazinone polyarylether, wherein the functional coating comprises a physically adsorbed bone morphogenetic protein layer with biological activity. The protein layer with the biological activity comprises bone morphogenetic protein, collagen, osteopontin, plasma fibrinogen and the like, and the surface of the phthalazinone polyarylether is loaded with the protein layer through a physical adsorption mode. The surface physical adsorption of the protein involves that the protein is adsorbed to functional groups or monomolecular layer with the active functional groups on the surface of the phthalazinone polyarylether. The three-dimensional surface structure and thefunctional coating can improve the osteogenic activity of polyarylether.
