Özet:

In this study, the organomodified clay (OVHAC) was synthesized by the cation exchanging of sodium montmorillonite clay (Na-MMT) with the quaternary ammonium salt, vinylbenzyldimethylhexadecylammonium chloride (VHAC) Polystyrene-clay nanocomposites (PS/OVHAC) were synthesized by in situ polymerization method. Organomodified montmorillonit clay and PS/OVHAC 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. Thermal behaviors and thermal degradation activation energies of nanocomposites were determined by thermogravimetric analysis method (TGA). Theoptical characterization of polymer thin films prepared by spin coating technique was tested with a UV-VIS spectrophotometer at 340 nm-700 nm wavelength range.
