Preparation, Characterization of Organo-Montmorillonite under Focused Signal-Mode Microwave Irradiation

Abstract:

In this paper，the organo-montmorillonite (OMMT) was prepared by cation exchange reaction, using sodium montmorillonite (Na+-MMT) and cetyltrimethylammonium bromide(CTAB) as all intercalation agent under precision microwave organic synthesis system. The structure of the montmorillonite was characterized by X-ray diffraction (XRD)、infrared spectrum (IR)、thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). The results show that the intercalation is successful, the CTAB as a organic modifier introuduced into lattice layers of montmorillonite by cation-exchange reaction and the surface morphology of OMMT is complete exfoliation, the distance between the lattice layers of montmorillonite has been greatly increased.
