摘要
利用光引发聚合和热引发聚合研究了单体(MMA)和蒙脱土(Mot)插层复合材料(PMMA/Mot)的制备问题。用小角X光衍射技术对两种产物内蒙脱土的结构进行了表征。结果表明,蒙脱土经改性后能很好的使聚合单体插入蒙脱土层内并在光或热的作用下“就地”发生聚合反应生成复合材料,利用DSC、SEM研究了产物的结构和形态,并对两种聚合方法制备蒙脱土纳米复合材料的特点进行了初步讨论。
The preparation of polymer/montmorillonite(PMMA/Mot)intercalation composite was studied by means of photo-polymerizatio and hot-polymerization. Small angle X-ray diffraction technique was applied to the structurl characterizations of the prepared products. Results indicated that after the surface modification of the montmorillonite the monomer was able to intercalate into the layers of Mot and to polymerize 'in situ' to prepare composite materials. The morphology and structure of the sample were studied by means of DSC and SEM. The advantages and disadvantages of the two methods for the preparation of these composite materials were discussed preliminary.
