Abstract
Section titled āAbstractāDetonation nanodiamonds hard-hydrogels are aggregates of polyhedral particles of sp3-hybridized-carbon coated by atomically thin sp2-hybridized carbon. Electronic properties of diamond are sensitive to water in the surrounding environment. The effect of adsorbed water on the electrical conductivity of detonation nanodiamonds was studied by exposure to humid air after thermal treatment in vacuo. The electrical conductivity increases with heating and decreases during the isothermal treatment at 393 K due to release of strongly adsorbed water, and gradually increases on exposing to humid air, indicating adsorption of water molecules on micropores and mesopores in the nanodiamond aggregates. Keywords: Nanodiamonds, Electrical conductivity, Adsorbed water, Micropore, Graphene-like carbon
