| 摘 要： | 采用化学镀法制得了表面包覆银层的导电磁性聚甲基丙烯酸甲酯(PMMA)微球。对粗糙度不同的微球进行镀银,研究了银在微球上的沉积机理。表面改性使磁性PMMA微球功能化,具有和银强烈结合的能力,从而得到包覆均匀的导电磁性微球。研究了硝酸银和磁性微球的含量对包覆效果及导电性能的影响,并通过SEM和EDS对镀银磁性微球的表面形貌及组成进行了分析。

| Abstract: | Silver coated magnetic polymethylmethacrylate(PMMA) micro beads were prepared by chemical reduction.The mechanism of the deposition of silver particles was investigated.The experiment shows that surface roughness of the micro core bead can enhance the deposition or coating coverage and treatment of surface of the micro core bead can enhance interaction between the the micro core bead and silver atoms,leading to an uniform deposition or coating.The effects of the introduced weights of AgNO3 and the core bead... |
