| 摘 要： | 以煤系高岭土为主要原料、二甲基亚砜(DMSO)为插层剂,制备出煤系高岭土/DMSO插层复合材料。利用X射线衍射、红外光谱和差示扫描量热-热重分析对插层复合物进行了研究。结果表明,DM-SO分子成功地插入了高岭石层间,与高岭石的内表面羟基形成新的氢键,并使高岭石的层间距从0.714nm增大至1.121nm,脱羟基温度由541℃左右降低至523℃。煤系高岭土/DMSO插层复合体于197℃左右发生DMSO的脱嵌作用。

| Abstract: | Kaolin/dimethylsulphoxide intercalation complex were successfully prepared by using kaolin from coal measures as the main raw material and dimethylsulphoxide (DMSO) as the intercalation agent.XRD,FT-IR and DSC-TG were used to investigate the intercalation complex.It is revealed that DMSO molecule intercalated successfully into the interlayer of kaolinite,and formed new hydrogen bonds with the inner surface hydroxyls of kaolinite.Thus led to the basal spacing of kaolinite increased from 0.714 to 1.121nm,and ... |
