Graft modification of graphene was facilely achieved by transesterification during melt blending processing between graphene oxide (GO) and polycarbonate (PC). The prepared PC-graft-GO was found to be a high-efficient reinforcing nanofiller, up to 49% increment in tensile strength of PC nanocomposite films was observed at a content of 1.0% wt.% PC-graft-GO. The reinforcement is caused not only by the bearing effect of graphene itself but also by the nucleating crystallization effect of the PC-graft-GO.
