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.

One Step Synthesis, Characterization of Modified Montmorillonite with Hydrothermal-Assist for Triazolone Sustained Release System with pH Sensitivity

“…Among them, montmorillonite (MMT) with layered pores has high capacity, high surface area, high porosity, low cost and better surface activity [3], due to which it is a widely used adsorbent for treatment of toxic organic pollutants in water purification and remediation of industrial wastes [4,5]. In order to better utilization of MMT which must be organic treatment because montmorillonite has a hydrophilic oleophobic properties and compatibility with the organic material is poor [6]. And the nanocomposites of modified clays are known to exhibit remarkable improvement in strength/heat resistance, decrease in gas permeability/flammability, and increase in biodegradability [3] compared to their untreated counterparts.…”
