High Impact Polystyrene (HIPS) is one of the rubber reinforced plastics with excellent impact strength, processability and thermoforming properties. Polyhedral Oligomeric Silsesquioxane (POSS) has Si-O-Si cage nanostructure (Si8O12) with functional groups that link to Si on its cage structure. POSS is an organic/inorganic hybrid material that satisfies not only the heat resistance and oxidation stability but also the processability, toughness and the enhanced thermal properties of hybrid materials POSS has been used as a additive for making hybrid materials to enhance the thermal and mechanical property. In this study, we tried to prepare HIPS/POSS composites with various ratios of Octa phenyl POSS to improve the mechanical and thermal properties of composites. The properties of HIPS/POSS nanocomposites were characterized by viscometer, FT-IR, NMR, TGA, XRD and SEM. In addition, the mechanical properties of have been characterized through ASTM D638 and ASTM D256. |
