Polymer matrix based nanocomposites have become a prominent area of current research and development due to significant improvement in polymer properties at very low filler contents. In present work Polymethylmethacrylate-Zinc oxide (PMMA-ZnO) nanocomposites have been prepared via solution casting method. X-ray diffraction (XRD) pattern confirms the formation of nanocomposites. Thermal characterization of PMMA-ZnO nanocomposites have been carried out using Differential Scanning Calorimeter (DSC). Results reveal that the glass transition temperature (T g) increases with the increase of heating rate and ZnO content due to stiffening of polymer chains. An effort has also been made for the non-isothermal kinetics at glass transition using Kissinger, Moynihan and Lasocka model.
