▎ 摘　　要

Graphene oxide/cyanate ester/epoxy nanocomposites were successfully synthesized. The prepolymers of the nanocomposites were tested with a non-isothermal differential scanning calorimetry (DSC). The graphene oxide played a role of catalyst in the curing process. The mechanical and thermal behaviors of the nanocomposites were investigated.. The results showed that the mechanical properties and storage modulus of nanocomposites were good with appropriate content of the matrixes. The glass transition temperature (T-g) and thermal stability of the nanocomposites were found to be lower than those of the pure cyanate ester resin.
