Polyhedral oligomeric silsesquioxane (POSS) which acts as a building block for nanocomposites owing to their nano size, high symmetry, and three dimensional figure. POSS, unlike other nanoparticles are easily dispersed in a wide range of polymer matrices which can be done by modifying chemical structure of POSS molecule for their compatibility with the specific polymer resin. POSS compounds give better mechanical stability, electrical and optical properties with an organic matrix. They are widely used in t
