Abstract:
1. A method for producing a biomaterial having a substrate made of a metal, an alloy or a ceramic material and a biocompatible material layer laminated at appropriate positions on the substrate, comprising the steps of: (a) plasma-treating the substrate made of a metal, an alloy or a ceramic material containing a metal component or a metal oxide capable of forming hydroxyl groups to form hydroxyl groups on the surface of the substrate; (b) applying a solution containing a binder constituent to the substrate and then drying the solution to form a binder layer thereon, the binder constituent being an organic compound having carboxyl groups on one terminal and methacrylic groups or methylene groups on the other terminal; and (c) immersing the substrate in a solution containing a biocompatible material and a photo-initiator and then polymerizing the biocompatible material monomer on the binder layer by UV irradiation to graft-coat the biocompatible material layer on the binder layer.
