A method for treating surface of base material, comprising: a diamond-like carbon film (a DLC film) formation step of forming a diamond-like carbon film on a surface of a base material an activation step of disconnecting a carbon to carbon bond of the diamond-like carbon film and generating on a surface of the diamond-like carbon film a reactive region which serves as a polymerization starting point and a polymerization step of polymerizing monomers using the polymerization starting point to graft the monomers to the surface of the diamond-like carbon film. Consequently, there is obtained a base coated with a DLC film which is modified with polymers that are hardly detached therefrom.一種基材之表面處理方法,其包括:在基材表面形成類鑽碳膜(DLC膜)的類鑽碳膜形成步驟,切斷前述類鑽碳膜之碳-碳鍵結,以在前述類鑽碳膜表面產生成為聚合開始點的反應性部位之活化步驟,以及使用前述聚合開始點來聚合單體,藉此將前述單體之聚合物接枝至前述類鑽碳膜表面的聚合步驟。經由此,能夠實現以不容易脫離的聚合物修飾的DLC膜所施加塗層的基材。11...基材21...反應室22...真空幫浦23...電極24...電極25...高頻電源26...匹配網路(matching network)
