【 摘 要 】

Graphene with two dimensional structures is a very exceptional material, since it has advantage of being excellent conducting material. Few layer of graphene sheets (FLGS) have been successfully prepared by an electrochemical method directly from graphite using oxalic acid as electrolyte. The prepared few layer FLGS have been characterized by X-ray diffraction(XRD), UV-Vis spectroscopy, field emission scanning electron microscope(FESEM), transmission electron microscope(TEM). The characterization reveals that the prepared FLGS is very good in quality. The measured current (I) vs voltage (v) shows that FLGS are highly conducting in nature. The hydrophobicity/Hydrophilicity of the prepared FLGS have been investigated for various applications.
