Polyacrylamide grafted graphene (PAM-g-graphene) from graphite oxide (GO) was successfully prepared by γ-ray irradiation with acrylamide monomers in aqueous at room temperature in this paper. Our strategy involves the PAM chains graft on the surface and between the layers of GO by in situ radical polymerization which led to the exfoliation of GO into individual sheets. Results show that the degree...
Graphene nanostructures with notched edges and nanopore defects were produced by the γ-ray irradiation of the graphite oxide in polar solvents. Because of the grafting of the long polymer chains, the thickness of the graphene monolayers is shown to be significantly increased. In addition, the graphitization degree got increased in unetched regions of the irradiated graphene due to the annealing effect...
