【摘要】 用化学分析、ＩＲ、ＸＲＤ等手段研究了高岭土一聚丙烯酰胺夹层复合物的合成过程。通过对高岭土一ＤＭＳＯ（二甲亚砜）中间复合物的置换反应，将丙烯酰胺单体引入高岭土层间。ＩＲ谱显示出有机物分子与高岭土的外羟基可能以氢键形式相互作用；ＸＲＤ谱表明夹入有机分子后，高岭上层间距ｄ＿（００１）值增大。通过适当的热处理，实现了丙烯酰胺单体在高岭土层间的聚合，增强了复合物结构的稳定性。更多还原

【Abstract】 Chcmical Analysic, Infrared Spectroscopy(IR) and X-RayDiffraction(XRD) have been used to study the preparation process of kao-linite-polyacrylamide intercalation compound.Acrylamide monomer was int-ercalated by displacing DMSO from kaolinite-DMSO intercalation compound.IR spectroscopy showed the formation of hydrogen bonds between the organicmolecules and the external hydroxyls of kaolinite. When the organic mole-cules were intercalated, XRD pattern showed the increasing of the basalspacing of kaolinite. After the kaolinite-acrylamide intercalation compoundwas properly heated,the polymerization of acrylamide monomer between thelayers of kaolinite was completed. The resulted kaolinite-polyacrylamideintercalation compound was resistant to decomposition by water washing.更多还原
