摘　　要：利用微波能量,快速制备了高岭石/DMSO插层复合物,并以其为前驱体,在熔融状态,微波诱导聚乙二醇(PEG)置换出高岭石层间的DMSO,微波继续协同PEG作用,可以实现其对高岭石的剥片。同时提出了微波作用机理和微波条件下插层物对高岭石的剥片机理。采用X-射线衍射、FTIR光谱、TG-DTA、TEM等技术对插层复合物进行了表征。Kaolinite/DMSO intercalation composite, a precursor for kaolinite exfoliation, was prepared rapidly by using microwave method. The kaolinite exfoliation was realized by intercalation of the precursor with polyethylene glycol （PEG） at melting state by microwave radiation. The intercalated and exfoliated composites were characterized by FFIR, XRD, TG-DTA and TEM techniques. The intercalation and exfoliation mechanism under microwave radiation was suggested.
