Enhancement of polymer properties by use of different types of nanosized fillers has attracted a growing attention of scientists recently. Polymer based nanocomposites have shown improvement in properties as compared to conventional scaled composites because of the length scale of interaction between the nanofillers and the polymer matrixes. Efforts are made to fully understand the relationship between structure and properties of such polymer based nanocomposites. Nanocomposites of Polystyrene as matrix and MethacrylPOSS (MPOSS) as the nanofiller and crosslinker were synthesized. For preparation of the nanocomposites, different concentrations of MPOSS have been applied. In order to investigate the structure-property relationships of the nanocomposites, several methods such as dielectric relaxation spectroscopy, fourier transform infrared spectroscopy, differential scanning calorimetry, and thermal gravimetric analysis have been employed.
