| 摘要 |
使用丙烯酸或丙烯酸酐亲水化一本体之复数表面，此使用包含：藉由PECVD利用高频电浆预涂布该些表面，其中藉由PECVD的此预涂布步骤进行少于10 分钟的时间；接着后续涂布该本体之已预涂布的该复数表面，其中用以预涂布之该高频电浆系由一惰性气体与一第一气体所构成的一气体混合物所产生，该第一气体系由具有生物相容性、可聚合、含羧基团的单体所形成，其中该后续涂布步骤系藉由CVD利用实质上由丙烯酸或丙烯酸酐单体所构成的第二气体进行，其中并不存在先前的电浆活化步骤，在此电浆活化步骤中不存在该第一气体或具有少于10%之由该单体所形成之该气体。; and then follow-up coating the pre-coated surfaces of the body, wherein the high frequency plasma used for pre-coating is generated from a gas mixture composed of an inert gas and a first gas formed of biocompatible, polymerizable, carboxy group-containing monomers, wherein the follow-up coating is made by CVD using a second gas substantially consisting of the acrylic acid or acrylic acid anhydride monomers, and wherein there is no preceding plasma-activation step in the absence of the first gas or with less than 10 % of the gas formed of the monomers. |
