| Research Abstract |
Photo-induced graft polymerization of 2-methacryloyloxyethyl phosphorylcholine (MPC) has been developed as a novel technology for reducing wear and increasing biocompatibility of orthopaedic bearings. In this study, the effects of MPC concentration and photo-irradiation time on graft polymerization, and the resultant properties of the grafted poly (MPC) layer have been investigated. Poly(MPC) layer thickness can be controlled by changing these conditions. In addition, we have evaluated the novel bearing surfaces of the artificial hip joint. From the results of this study, we concluded that the MPC grafting is a promising method to achieve improved wear-resistance and cartilage-mimicking bearing surfaces of the artificial joint.
