Different Content

A series of cyanate ester resin (CE) based organic-inorganic hybrids containing different content (0, 5, 10, 15 and 20 wt%) of epoxy functionalized polyhedral oligomeric silsesquioxane (POSS-Ep) were prepared by casting and curing. Impact and flexural strengths of the hybrids were investigated. Results showed that CE10 containing 10wt% of POSS-Ep displayed not only the optimum impact strength but the optimum flexural strength.

Oligomeric Silsesquioxane

Poly(butyl acrylate-co-methyl methacrylate-co-octavinyl polyhedral oligomeric silsesquioxane) (OVPOSS-P(BA-MMA)) nanocomposites were synthesized by emulsion polymerization. The structures of nanocomposites were characterized by Fourier transform infrared spectrum (FTIR) and solubility experiment. It was shown that the network structures have been formed during the copolymerization. Dynamic mechanical analysis (DMA) was used to investigate the dynamic mechanical and thermal properties. The data indicate that the crosslinking density apparently affects the mechanical and thermal properties of OVPOSS-P(BA-MMA).

Oligomeric Silsesquioxane

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 oC, 44 oC higher than that of the pristine CE.
