摘要
Thin layers of graphite oxide sheets were dispersed in dim ethyl form amide and dielectrophoretically assembled onto predefined and opposing metal electrodes. The dielectrophoretic method resulted in the deposition of multiple layers of graphite oxide. After drying, the deposits were then reduced by thermal or chemical methods. Raman spectroscopy and electrical transport measurements revealed that the thermal reduction technique was more effective in restoring electrical conductivity than the chemical reduction method.
