摘要
采用乳液聚合法制备了苯乙烯-丙烯酰胺共聚物/蒙脱土纳米复合材料,研究了苯乙烯用量和体系pH值对复合材料剥离效果的影响;通过XRD、FT-IR和TEM对复合材料的层间结构、界面状态和共聚结构等进行了表征。结果表明:当丙烯酰胺与苯乙烯单体质量比为1∶1～1.4∶1、反应体系pH为1～9时,膨润土层间域发生了剥离,苯乙烯-丙烯酰胺发生了共聚反应,且剥离膨润土以片层结构均匀分散在聚苯乙烯-丙烯酰胺基体中。
Polystyrene/Montmorillonite acid-acrylamide nanocomposites have been prepared by emulsion polymerization. By XRD, FTIR and TEM of composite between layers of the structure, the interface state and eopolymerization structure characterization. The results shows that：when acrylamide and styrene monomer mass ratio of 1 ： 1-1.4 ： 1, reaction system pH for 1 -9, Bentonite fihn layer is peeled off and Styrene and acrylamide was reaction that stripping bentonite to slice layer structure equably dispersed in polystyrene acid-acrylamide matrix.
