Effect and characterization of acidification treatment on the intercalation of montmorillonite

Montmorillonite(MMT) is treated by the intercalation of organic using the method of solution intercalation.It included acidification and organization treatment.The results showed that the acidification can not only expand the interlayer spacing of MMT,but also effectively improve the compatibility of organic montmorillonite in toluene,xylene and other organic solvents.The microstructure and morphology of organic montmorillonite were investigated by TGA,XRD and FT-IR.Furthermore,the acidification mechanism was also studied.
