The unique electronic property of graphene sheets provides potential applications in nanocomposites and fabricating various nicroelectrical devices, such as field-effect transistors, ultrasensitive sensors, and electromechanical resonators. Several effective techniques have been developed for preparing graphene sheets. Among these technique, mechanical exfoliation can produce pure graphene and epitaxial graphene sheets have been prepared by treatment of silicon carbide wafers at high temperature. Recently, graphene sheets have been developed by chemical reduction method from graphene oxide. In this work, we have synthesized graphene sheets based on mechanical exfoliation and chemical reduction methods. Graphene sheets were characterized by field-effect scanning electron microscope (FE-SEM). The size of graphene sheets was from few hundreds nanometer to decades micrometer.
