The graphene quantum dots may provide intriguing nanoscale molding material with low density for various composite applications. Because of the wide use of commercial, military and scientific electronic devices and communication instruments, electromagnetic interference shielding of radio frequency radiation continues to be a serious concern for modern society. Compared with conventional metal-based shielding materials, conducting carbon composites are lightweight, resistant to corrosion, and flexible and offer processing advantages (Carbon, 47, 922, 2009). The shielding effectiveness of graphene quantum dots with g-C3N4 depends on the molding’s intrinsic conductivity and dielectric constant. Thus, it is expected that the use of atomic thick graphene quantum dots, with large aspect ratio and high conductivity, would provide a high shielding. In this study, we report the first result of shielding of g-C3N4 composites based on graphene quantum dots. |
