Polymer sliding material, artificial joint member, medical appliance, and manufacturing method therefor

摘要

Disclosed is a sliding member with excellent durability and capable of maintaining wear resistance over a long period of time. Further disclosed is an artificial joint member for which the film thickness of the polymer base material is reduced. Further disclosed is an artificial joint which is capable of demonstrating high lubricity, biocompatibility, and resistance to dislocation after introduction into the body. Further disclosed are a medical appliance material and a medical appliance which demonstrate excellent biocompatibility. The sliding material or the medical appliance material is formed by a polymer layer or a biocompatible material layer (B) being provided by coating at least a portion of the surface of a polymer base material (A), the surface of which has a ketone group, and the polymer layer or biocompatible layer (B) is characterized by being formed by surface graft polymerization, wherein the polymer base material (A) is immersed in a reaction system which contains a monomer (C), the polymer base material (A) is exposed to light, and polymerization of the monomer is initiated from the surface of the polymer base material (A). Using the sliding material or medical appliance material, an artificial joint member, an artificial joint, a medical appliance material, and a medical appliance are manufactured.

主权项

1. A polymer sliding material comprising a polymer substrate (A) having ketone groups on the surface thereof and a coating layer (B) which coats at least a portion of the surface of the polymer substrate (A), wherein the coating layer (B) is formed by a surface graft polymerization comprising immersing the polymer substrate (A) in a reaction system containing a monomer (C), irradiating the polymer substrate (A) with light which is an ultraviolet ray or a visible ray, thereby polymerizing the monomer from the surface of the substrate.
