摘　　要：以紫外 /可见光分光光度计为检测手段 ,研究确定了水 /Span85 - Tween6 0 /环己烷反相微乳液体系的适宜条件如乳化剂含量、HL B值和溶水量值 ;进而在其中进行丙烯酰胺(AM)聚合反应和 Ag Cl、Zn S沉淀反应 ,制备了 Ag Cl/PAM、Zn S/PAM纳米复合微粒 ,并采用透射电镜 (TEM)Ultraviolet(UV)/visible light spectromometer was applied in investigation of H 2O/Span85 Tween60/cyclohexane reverse microemulsions.Surfactant content,hydrophilic/hydrophobic balance value (HLB) and water content R ([H 2O]/[surfactants],molar ratio) were optimized.Based on the former research,further experiments were carried out in the optimized system and acrylamide polymerization was initiated in reverse micellar microreactors and AgCl/PAM,ZnS/PAM composite nanoparticles were successfully prepared.The morphology of nanoparticles was observed by transmission electron microscope (TEM).
