study on the fabrication of graphene using the exfoliation method

Abstract

The effect of various synthesis conditions in the fabrication of graphene using the exfoliation method has been investigated. The graphite oxide and graphene fabricated by various synthesis conditions were identified by SEM, FE-SEM and XRD. Graphite oxide was fabricated from graphite using chemical exfoliation and graphene was manufactured from graphite oxide by thermal exfoliation. As a result, graphite oxide was well formed from graphite and graphene could be obtained from graphite oxide. And it was found that the interlayer spacing between the graphene layers depended on the reaction time and particle size, regardless of the reaction temperature from 5℃ to 25℃.
