摘要/Abstract

摘要： 用两种光聚合法研究了蒙脱土插层复合材料的制备.用小角X光衍射技术对产物内蒙脱土的结构进行表征,结果表明,蒙脱土经改性后能很好地使聚合单体及预聚物插入黏土层内并在光照下"就地”聚合生成光聚合复合材料.对光聚合法制备蒙脱土纳米复合材料的优缺点进行了初步讨论.

关键词: 光聚合, 蒙脱土, 插层, 小角X-光衍射技术, 纳米复合材料

Abstract: The preparation of polymer/montmorillonite intercalation composite materials has been studied by applying two kinds of photo-polymerization reaction (photo-acid generation and photo radical generation)in this work.Small angle X-ray diffraction technique was used for the structural characterization of montmorillonite contained in the products.Results indicated that after surface modification of montmorillonite the monomer(methyl methacrylate,MMA)and the prepolymer (m cresol/HMMM) were able to intercalate into the layers of the clay and to polymerize/in “situ” to obtain photo-polymerized composite materials.The advantages and the demerits of the method of photo-polymerization for preparation of these composite materials have been discussed preliminaryly.

Key words: photo-polymerization, montmorillonite, intercalation, small angle X-ray diffraction technique, nano composite materials
