Abstract

Nanocomposites, are mixed materials synthesized from one or two polymers blended in optimized percentages and Organophilic clay. The objective of this study is to use the Organophilic clay (Maghnite: montmorillonite) in the presence of tow monomers to obtain a copolytetrahydrofuran- styrene nanocomposite by in-situ polymerization. Organophilic montmorillonite (O-MMT) was prepared by ion exchange between Na+ ions in the clay hexadecyltrimethylammonium bromine cations in an aqueous medium. The organophilic MMT particles were easily dispersed in styrene (St) and tetrahydrofuran (THF) monomer. The structure of obtained modifier was investigated by proton nuclear magnetic resonance (RMN1H), Fourier-transform infrared (FT-IR) spectroscopy. The exfoliating structure of nanocomposite was probed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The Thermal stability were also investigated with thermogravimetric analyzer (TGA), comparing with pure polystyrene, the nanocomposite showed much higher decomposition temperature.
