Synthesis and characterization of polymer clay composites

In this study, synthesized N-(4-bromophenyl)-2-methacrylamide (BrPMAAm) and N-(4-fluorophenyl)-2-methacrylamide (FPMAAm) monomers are polymerized via free radical polymerization. Montmorillonite-containing raw clay (NaMT), pure clay (SMT) and synthesized organoclay (OSMT) interlayer distances for the structure elucidation Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analyze were determined. Later, composites of BrPMAAm and FPMAAm monomers were obtained using 2, 4, 6 and 10 % organoclay by mass with in-situ polymerization. The synthesized polymer-clay composites were characterized by FTIR, XRD and scanning electron microscopy (SEM) analysis. The synthesized polymer-clay composites which are organophilic clay modified with hexadecyltrimethylammonium bromide (CTAB), showed exfoliated structure. It was evidenced by XRD. Homopolymer and 10 % organoclay doped polimerlerin molecular weight to were determined using Gel Permeation Chromatography (GPC). Thermal properties of polymers were performed using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Thermal properties of the polymer were also developed.
