  • Reduced graphene oxide/polyimide(rGO/PI) composites were prepared by the incorporation of the PI by in-situ polymerization and solution blending methods. The influence of these methods on the mechanical and electrical properties of the composites was investigated. Results indicate that the addition of the rGO to PI significantly changes its mechanical and electrical properties. The rGO is more homogeneously dispersed in the PI, its re-aggregation in the PI is significantly inhibited, and the tensile strength and electrical conductivity of the composites are higher for the in-situ polymerization method than the solution blending one. The tensile strength and electrical conductivity of the composite reach the highest values of 132.5 MPa and 6.87×10-4 S·m-1 with rGO additions of 1.0 and 3.0 wt%, respectively for the in-situ polymerization method, which are 68.8% and 8 orders of magnitude higher than the corresponding values for pure PI.
