HIGHLY LUBRICATING SLIDING MEMBER AND ARTIFICIAL JOINT USING SAME |
摘要 |
<p>Disclosed are: a sliding member which is capable of maintaining wear resistance over a long period of time; an artificial joint member in which the polymer base is reduced in thickness; and an artificial joint which exhibits high lubricating properties in the body, biocompatibility and resistance to dislocation. Specifically disclosed is a polymer sliding material which has a coating layer (B) that is composed of a graft polymer containing a phosphorylcholine group and having a density of at least 1.4 g/cm 3 on at least a part of the surface of a polymer base (A) that has a ketone group on the surface. The sliding material can be obtained by immersing the polymer base (A) into a liquid of a monomer (C) that has a phosphorylcholine group, and causing surface graft polymerization by irradiation of light. Also specifically disclosed are an artificial joint member using the polymer sliding material, and an artificial joint.</p> |
