Preparation and Research of Coupling Agent Modified Organophilic Montmorillonite

Abstract:

A novel method is proposed to modify montmorillonite with coupling agents and Hexadecyl triphenyl phosphonium bromide surfactants made by our group (named P-surfactant in the following). The structure of organophilic montmorillonite (OMMT) was investigated by FT-IR, XRD and TG. The FT-IR shows the coupling agents were inserted between the layers of MMT and reacted with –OH of MMT. The results of X-ray diffraction shows that the coupling agents were all intercalated into the layers of MMT. The interlayer spacing of montmorillonite increases to 4.00 nm, the effect of modification is well. The results of TG showed the thermal stability was better.
