| 摘 要： | 采用两步法的简单路线制备出银纳米粒子包覆的聚苯乙烯(PS)微球,首先通过乳液聚合法合成出聚苯乙烯微球;然后对苯乙烯进行敏化和活化,搅拌下加入银的还原液,从而制备出Ag-PS核壳结构的纳米微球.同时借助于TEM、UV-vis、 FE-SEM进行表征,分析其微观结构.结果表明,所得的聚苯乙烯微球粒径约为40nm;聚苯乙烯/银核壳结构纳米微球粒径为45～350nm,银层厚度可随意调控.

| Abstract: | A two-step process was developed to fabricate PS/Ag core-shell nanoparticles.Firstly PS microparticles prepared in latex are sensitize and activation.Then the liquid with Ag are added in the PS with unending stirring.At last PS/Ag core-shell nanoparticles are fabricated.The products were characterized by transmission electron microscopy(TEM),field emission scanning electron microscopy(FE-SEM) and ultra violet-visible light spectrograph(UV-vis).The results shows: The PS microparticles we prepared are only 40... |
