| 摘 要： | 采用化学镀方法,对微米级丙烯酸酯橡胶(ACM,Acrylate rubbers)微球进行表面金属铜镀覆;通过对镀铜反应进程的控制,制备出了镀层致密、包覆均匀的低密度ACM核-铜壳结构复合导电微球(简称镀铜ACM复合微球);研究了镀铜ACM复合微球表面铜镀层的结构、形貌及微球的电性能.结果表明:应用化学镀的方法可以对ACM微球进行表面金属铜镀覆;通过控制镀液中OH-的补加量,能够准确控制化学镀铜反应进程及表面镀层包覆程度;不同包覆程度的镀铜ACM复合导电微球的体积电阻率均随外加压力增大而降低,几乎不随通电时间变化,但随温度升高表现出阻-温特性.

| Abstract: | Electroless copper plating on acrylate rubber(ACM) microspheres of micron scale was studied.By introducing a reaction control method,the continuously and uniformly covered ACM conductive microspheres with low density and core-shell structure were achieved.The morphology and composition of Cu coatings and the electrical properties of the Cu-coated ACM microspheres were investigated.It was found that Cu can be plated on the surface of ACM microspheres by electroless plating.The reaction process of electroless... |
