| 摘 要： | 利用二甲亚砜、丙烯酰胺、硅烷等多种有机改性剂对高岭土进行了有机夹层、吸附改性。经有机改性。高岭石的层面间距d（001）可增大到1.1454nm，并且与丙烯酰胺加热后形成稳定的了聚丙烯酰胺-高岭土有机无机复合材料，与硅烷形成稳定的有机无机复合体。改性后的高岭土与有机物的相溶性大大提高，从而为更好地开发应用高岭土做准备。

| Abstract: | The study on intercalation or adsorption of some organic compounds in kaolinite or its surfaces and its stability is made in this paper. The organic compounds include dimethyl sulphoxide, acrylamide and silane coupling agents. The c-axis spacing in kaolinite expands to a large value of 1.1454 nm as a result of intercalation of polar compound into kaolinite. Acrylamide can be intercalated into kaolinite by virtue of dimethyl sulphoxide and is stable in kaolinite after being heated. Adsorption of silane coupling agents onto kaolinite surfaces is also stable and results in the formation of organic kaolinite. |
