Abstract :In the present study, the synthesis, characterization, thermal and optical properties of polyinsert ignore into journalissuearticles values(methyl methacrylate);insert ignore into journalissuearticles values(PMMA);/organomodified montmorillonit clay insert ignore into journalissuearticles values(OMTAB); nanocomposites were investigated. PMMA/nanoclay composites were synthesized by in situ polymerization method. Organomodified montmorillonit clay and PMMA/OMTAB nanocomposites were characterized by FTIR technique. The interlayer spacing of the organoclay platelets and the polymer clay nanocomposites were determined by X-ray diffraction spectroscopy. It was determined that the clay dispersion in the polymer matrix was exfoliated behavior. Thermal behaviors and thermal degradation activation energies of nanocomposites were determined by thermogravimetric analysis method insert ignore into journalissuearticles values(TGA);. Polymer/nanocomposite thin films on the quartz surface were prepared by spin coating technique. The optical properties were obtained by measuring transmittance values in a UV-VIS spectrophotometer.
Keywords : Polymer clay nanocomposites, exfoliation intercalation, thermal degradation kinetics, optical properties
