Enhanced thermal properties of cyanate ester resin by epoxy-functionalized POSS

摘要：

　　Cyanate ester resin (CE)/epoxy functionalized polyhedral oligomeric silsesquioxane (POSS-Ep) organic-inorganic hybrids were prepared by casting and curing.The hybrid resin systems were studied by gel time test to evaluate the effect of POSS-Ep on curing reactivity of CE.Impact and flexural strengths of the hybrids were investigated.The thermal properties of the hybrids were studied by thermogravimetric analysis (TGA).TGA results show that CE10 also possesses the best thermal stability.The initial temperature of decomposition (Ti) of CE10 is 426 ℃,44 ℃ higher than that of the pristine CE.
