Two-step reduction of self-assembed three-dimensional (3D) reduced graphene oxide (RGO)/zinc oxide (ZnO) nanocomposites for electromagnetic absorption

Graphene oxide and zinc oxide nanoparticles have formed a three-dimensional nanocomposite with a high performance of electromagnetic absorption via a hydrothermal process. UV-irradiation removed the remaining oxygen functional groups from the skeleton of the reduced graphene oxide.
