| 摘 要： | 以聚乙烯吡咯烷酮为分散剂,偶氮二异丁腈为引发剂,无水乙醇为分散介质,通过分散聚合,制备出表面光滑、分散均匀的聚苯乙烯(PS)微球。在PS微球表面化学镀Ni,制得具有较好导电性能的PS/Ni复合粒子。研究了PS微球表面镀Ni前后的表观形貌及晶相变化,并分析了制备工艺对复合粒子导电性能的影响。分析表明,PS微球表面镀Ni的优化工艺为:PS/NiCl2·6H2O质量比4∶7,络合剂用量2 g,NH3·H2O用量30mL。

| Abstract: | The PS microspheres with the smooth surface and uniform size were prepared by the dispersion polymerization technique in the presence of PVP, using 2-methylpropionitrile as initiator, anhydrous alcohol as the dispersion medium . After surface treatment, PS / Ni composite particles with characteristic of high conductivity were prepared by chemical plating process. The results show that the surface morphology and phase change of PS microspheres before and after nickel plating were studied and the effect of preparaction process on conductivity of composite was analyzed. The results show that the optimized process is: PS / NiCl2 ·6 H2O = 4 : 7 ( mass ratio) ,complexing agent dosage is 2 g, NH3 ·H2O dosage is 30 mL. |
