Progresses on Epoxy Resin Modified by Polyhedral Oligomeric Silsesquioxane

Polyhedral oligomeric silsesquioxane (POSS) was a novel organic and inorganic hybrids material developed in recent years. The structure and synthesis of polyhedral oligomeric silsesquioxane and the structure and synthesis of polymer composites based POSS was reviewed in the paper. The thermal properties,flame retardant and mechanical properties of the polymer modified by polyhedral oligomeric silsesquioxane would be improved,due to the rigid structure and steric hindrance of polyderal oligomeric silsequioxane. This paper reviewed the epoxy resin modified by polyhedral oligomeric silsequioxane.
