核-壳结构的氯化银/聚丙烯酰胺复合纳米粒子的制备与表征

Preparation and Characterization of AgCl/PAM Nanoparticle with Core-Shell Structure

摘要: 用反相微乳液作为模板制备了核-壳结构的氯化锯／聚丙烯酰胺(AgCI／PAM)复合纳米粒子。透射电镜(TEM)证实复合粒子为核-壳结构，平均直径约100nm。扫描电子显微镜(SEM)和X射线衍射分析显示，平均粒径约50nm的AgCl均匀分散在聚合物中。FTIR谱图表明：AgO与PAM之间存在较强的相互作用。用能级探洲光谱(Energy Detected Spectrum，EDS)和润湿分散实验比较了不同方法改性的复合粒子的表面结构与润湿性能。

Abstract: The surface of nano-AgCl modified by polyacryamide with microemulsion template has been performed. Transmission electron microscopy (TEM) analysis demonstrates that the composite is a core-shell structure of AgCl/poly acryamide ( PAM) composite nanopartic
