Intercalation and Exfoliation of Kaolinite through PEG by Microwave

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 character- ized by FTIR, XRD, TG-DTA and TEM techniques. The intercalation and exfoliation mechanism under microwave radiation was suggested.
