| titleOfInvention | Preparation method of bionic polyether-ether-ketone artificial joint mortar with soft-hard composite structure |
| abstract | The invention discloses a preparation method of a bionic polyether-ether-ketone artificial joint mortar with a soft-hard composite structure. According to the method, a hard polyether-ether-ketone or derivative artificial joint mortar cup is used as a matrix, a hole structure is built on the surface of the artificial joint mortar cup by adopting a laser punching method, then an ultraviolet irradiation graft polymerization technology is combined, a layer of soft hydrogel layer is prepared on the surface of the polyether-ether-ketone artificial joint mortar cup with the hole structure, and finally the hydrogel-polyether-ether-ketone composite material is immersed into an iron ion solution to reinforce the hydrogel layer, so that the bionic low-friction polyether-ether-ketone artificial joint mortar cup is obtained. The surface of the polyether-ether-ketone joint mortar cup is provided with the soft hydrogel layer, so that the surface wettability and the friction coefficient of the polyether-ether-ketone joint mortar cup are obviously improved on the basis of keeping the body performance of polyether-ether-ketone or derivatives thereof, the friction coefficient and the abrasion loss are effectively reduced, the soft hydrogel layer on the surface can protect a base body, and the bionic design of a natural joint lubricating system is realized from the structural and functional aspects. |
