화학적 박리법에 의한 그래핀 제조 및 응용에 관한 연구
- Alternative Title
- Study on the preparation of graphene by chemically exfoliated method and Its application
- Abstract
- In this study, the graphene was prepared by chemical and thermal exfoliation method using the modified Hummers method. The prepared graphite oxide and graphene were observed by SEM and XRD. Graphite oxide was made from graphite by the chemical oxidation, and graphene was manufactured from graphite oxide by thermal exfoliation method. As a result, it is confirmed that graphite oxide was well formed from graphite, and the graphene could be obtained from graphite oxide. Graphene/epoxy resin composites was manufactured using the fabricated graphene and the mechanical and electrical properties of that has been investigated.
