| 英文摘要 | Hydrated graphite oxide samples containing different concentrations of functional groups were investigated with a range of experimental techniques including complex impedance spectroscopy. The activation energies in their conductivities increase with their epoxide concentrations and closely match those in dielectric relaxation. They appear to conduct by a Grotthuss mechanism, involving the exchange of protons between neighboring water molecules and the rotation of water. In the region below room temperature, this conductance is not limited by proton hopping but by water rotation about its hydrogen bond to an epoxide group attached to a graphene plane.
