Effect of amino-functional polyhedral oligomeric silsesquioxane ontoughness of epoxy resin

Epoxy resins have outstanding properties with variety uses especially in high performanceengineering applications. However, high degree of crosslinking density make them rigid and brittle.Many attempts have been used to improve mechanical properties, especially toughness. In the currentwork, synergistic properties of using the polyhedral oligomeric silsesquioxane nanostructure (POSS)and polyether amine chains has been used to improve toughness. The results indicated that using thesynthesized structure (GA-POSS) as co-curing agent improves toughness and it has effect on themorphology of the hybrid.
