Abstract

The dielectric constants of graphene oxide’s at 9.231GHz have been studied by cavity perturbation methods. 5g/ml and 2.5g/ml two different concentration graphene oxides were prepared and instilled into glass capillaries with the diameter of 0.9mm and 0.5mm. Based on the Independently developed heating system and temperature display device, the dielectric constants with different depth of microwave cavity were measured at different temperature from 18° to 38°. It found that the graphene oxide’s dielectric constants became lager when the depth increased in the cavity. In addition, it varied obviously when the diameters of the sample changed.
