Abstract：
Graphene oxide/bismaleimide(BMI) resin nanocomposites were prepared by solvent exfoliation and dispersion method. The nanocompoistes were characterized by XRD, TEM and TGA. In addition, mechanical properties of the nanocomposites were studied in this paper. The results show that graphenen oxide can be obtained by ultrasonic exfoliation of phenyl isocyanate-modified graphite oxide in N, N-dimethylformamide solution. The nanocomposites exhibit better mechanical properties than the neat BMI resin. When the content of graphene oxide is 1% of BMI resin, the nanocompoistes have the best mechanical properties, as indicated by that the tensile strength, flexural strength and impact strength of the nanocomposites arrive at 87.7 MPa, 142.1 MPa and 15.9 kJ/m2, respectively. In addition, the thermal stability of the nanocomposites is improved with graphene oxide content increasing. When the content of graphene oxide is 1.25% of BMI resin, the carbonization yield of the nanocomposites reaches 41.3% at 1000°C.
