Synthesis and characterization of poly(2-thiozyl methacrylamide) / sodium montmorillonite nanocomposites

In this study, 2-thiozyl methacrylamide based monomer was synthesized by reacting 2-amino thiazole with methacryloylchloride in the presence of triethylamine. Synthesis and characterization of 2-thiozyl methacrylamide-sodium montmorillonite nanocomposites were done. Synthesis of nanocomposites were done in three steps which are; purification and cation exchange capacity (CEC) determination of clay, organoclay synthesis and nanocomposite synthesis. Pure clay was dried, its CEC is determined and than used in organoclay synthesis. CEC determination was done as written in ANSI/ASTM C837-76 standard. In organoclay synthesis; surfactants were used which is long chained dimethyl N-octadeshyl ammonium chloride. Gallery distances of organoclay and nanocomposites were calculated by X-Ray Diffraction (XRD) analysis. Nanocomposite synthesis were done by in-situ polymerization. Composites; which contain varying amounts of clay by mass were characterized by XRD, thermogravimetric analysis (TGA) and scanning electron microscope (SEM). Also, pore size of nanocomposites were determined by BET analysis.
