摘　　要：采用工业微波快速制备了高岭石-二甲基亚砜(DMSO)插层复合物,并首次探讨了工业微波功率对插层效果的影响。以高岭石-二甲基亚砜(DMSO)插层复合物为前驱体,在熔融状态,微波诱导聚乙二醇(PEG)置换出高岭石层间的DMSO,微波继续协伺PEG作用,实现了其对高岭石的剥片。采用X射线衍射、FTIR光谱、TG-DTA、TEM等对插层复合物进行了表征。为微波制备高岭石插层复合物及其应用的工业化打下了一定的基础。This paper reports on a novel route to prepare kaolinite/polymer intercalation composite,and the effects that different microwave power have on the intercalation process.Kaolinite/DMSO intercalation composite.a precursor for kaolinite exfoliation,is prepared rapidly by using microwave method.The kaolinite exfoliation is realized by intercalation of the precursor with polyethyleneglycol (PEG) at melting state by microwave radiation.The intercalated and exfoliated composites are characterized by X-ray diffraction (XRD),thermal analysis (TG-DTA),FTIR spectra and transmission electron microscopy (TEM)techniques.The intercalation and exfoliation mechanism under microwave radiation is suggested.
