Abstract

In this work, the electrical conductance and induced current of 3-dimensional graphene foam (GF) are investigated when the mixture of water and ethanol flows through it. When different mixing ratios of ethanol: water (ethanol: water = 25:75, 50:50, 75:25, and 100:0 by volume) flow through the GFs, their electrical conductance are almost the same as that of original GF. Meanwhile, the induced current can be obtained when the mixture flows through the GF. The direction of induced current depends on that of the flow of mixture, the value of induced current has no matter with the flow direction of mixture but is closely related to the flow velocity and polarity of mixture. The mechanism of the induced electricity is discussed, which is attributed to the coupling of flowing solution molecules with the charge carriers of graphene at the solid/liquid interface. These results indicate that GFs have a bright potential application in realizing the self-powered function of nano/micro electromechanical systems (N/MEMS) in many special environments.
