摘要
使用氨丙基三乙氧基硅烷偶联剂改性空心玻璃微珠表面,然后直接实施化学镀银,借助红外光谱、扫描电镜和X-射线衍射测试手段对偶联改性效果、镀层表面形貌和结构进行了表征。测试结果表明,与胶体钯活化法和硝酸银活化法化学镀银相比,空心玻璃微珠偶联表面改性直接化学镀银的镀层更为致密、均匀,银利用率高,导电性好,结合力强。
Surface of hollow glass microsphere was firstly modified by silane coupling agent, and then applying electroless silver plating directly. Surface morphology and structure of the coating were charac- terized by FFIR, SEM and XRD techniques. Results showed that compared with the colloidal palladium activation and silver ammonium solution activation methods, this silane coupling method could result in a uniform and compact coating with superior conductivity, higher adhesion and better silver utilization.
