▎ 摘　　要

The grafting of graphene oxide (GO) with a cyclic ether monomer, epsilon-caprolactone (epsilon-CL), directly affords graphene-PCL nanocomposites. The resulting nanocomposites show good solubility in the solvents of polymers, exfoliation of graphene in the polymer matrix and excellent mechanical properties and robustness under bending.
