中文摘要：

采用一种新的化学镀法合成银壳包覆聚苯乙烯微球,通过三乙醇胺和银离子络合来减小反应的氧化还原电位差,降低银在改性聚苯乙烯微球表面的沉积速率.采用TEM、XRD、UV等测试手段对样品进行了分析和表征,并考察了不同反应条件对实验结果的影响.实验表明,该方法可在改性聚苯乙烯微球上包覆均匀的银层.

英文摘要：

Modified polystyrene microspheres with silver shells were prepared by a novel electroless plating approach using complexation mechanism of triethanolamine（TEA） and silver ion to reduce oxidation-reduction potential difference and slow down the deposition speed of silver on modified polystyrene spheres. These samples were characterized by TEM, UV, XRD, and the synthesis conditions were also investigated. Experimental results show that uniform silver shells can be deposited on the modified polystyrene spheres by this method.
