Synthesis and Characterizations of MmtO-Copolymer (St-THF) Nanocomposite

摘要

Nanocomposites are synthesized by one or two polymers and optimized organophilic clay proportions. The aim of Synthesis of the Organophilic clay (montmorillonite) with a two monomers to get a copolytetrahydrofuran- styrene nanocomposite by insitu polymerization. Organophilic montmorillonite (MmtO) was synthesized by ion exchange between Na~+ ions in the clay and HDTMAB alkylammonium cations in an aqueous medium. The MmtO were simply dispersed in two monomers: Styrene (St) and Tetrahydrofuran (THF). The Sample was investigated by proton nuclear magnetic resonance (RMN~1H) and infrared spectroscopy. The nanocomposite exfoliate arrangement of was delved by X-Ray Diffraction (XRD) and Transmission Electron Microscopy (TEM). The temperature degradation was also examined with Thermogravimetric Analyzer (TGA), the thermal stability of nanocomposite higher then polystyrene alone.
