Abstract: Kaolinite/NMF intercalation compound were prepared by magnetic stirring at room temperature.The change of characteristic groups and structure with intercalation and without intercalation were analyzed by the XRD、FTIR and TG-DSC. The results show that NMF get into the kaolinite layer,the intercalated rate is up to 92% and the layer space increased from 0.71 nm to 1.07 nm under stir for 24 h.As the time was extended,the intercalated rate decreased,but the order of crystallization increased.The intensity of OH...
