Effects of POSS Nanostructure on Morphology and Thermal Stability of Poly(vinyl alcohol)/POSS Nanocomposite

Semi-crystalline polymers consist of crystalline and amorphous domains have been extensively studied due to their practical applications. These kinds of polymers includepolyethylene, polypropylene, polystyrene, polyamide, poly (ethylene terephthalate), poly(trimethylene terephthalate) andpoly(vinyl alcohol) (PVA) [1]. Semi-crystalline polymer nanocomposites fabricate in order to improve the physical properties of pristine polymers. In recent years, Polyhedraloligomeric silsesquioxane (POSS) based materials have been studied widely. POSS can be effectively incorporated intopolymers by copolymerization, grafting or even blending through traditional processing methods [2,3].
