A diamond-like carbon film (DLC film) is formed on the surface of a base material made of an inorganic material, such as ceramics, or the like, or an organic material, such as resin, or the like. The surface of the resultant DLC film is treated with plasma, or the like, so as to be activated. Various monomers having biocompatibility, etc., are graft-polymerized to the activated surface of the DLC film, whereby a polymer layer is formed from the monomers grafted to the surface of the DLC film. Thus, the base material coated with the DLC film modified with a polymer which does not readily separate can be realized.
Il est prévu un film mince en forme de losange (film DLC) formé à la surface d'une base composée d'un matériau inorganique comme une céramique ou d'un matériau organique comme une résine, et la surface du film DLC est traitée et activée à l'aide de plasma ou équivalent. Divers monomères ayant une biocompatibilité et analogues sont polymérisés par greffage à la surface activée du film DLC, greffant ainsi des polymères desdits monomères à la surface du film DLC. On peut ainsi obtenir une base revêtue d'un film DLC modifié par des polymères à peine détachés de celui-ci.
