Abstract:
Stable and uniform dispersion of graphite nanoplatelets (GNPs, the diameter of 5-10 mu m) in organic solvent had been prepared. The dispersion of GNPs is improved remarkably with the assistance of dispersant and resin. The voltage generation for the movement of graphite nanoplatelets is observed in organic liquid. An induced voltage of similar to 90 mV has been generated, which is roughly three times higher than the voltage generation reported with multi-walled carbon nanotubes. The voltage generation increases linearly with increase of area and decrease of distance between two electrodes. Voltage generation mechanism may come from electrostatic interactions of the fluid species with the delocalized Pi electrons of the graphite from thermal excitation with the hot phonons produced by the friction of the moving liquid. Our work highlights the device potential for graphite nanoplatelets as sensitive flow sensors and for energy conversion. (C) 2009 Elsevier B.V. All rights rese!
