A study on interfacial behaviors of epoxy/graphene oxide derived from pitch-based graphite fibers

Graphene oxide (GO) is a versatile material with inherent unique properties that can be used in a wide range of applications. GO is produced from graphitic materials including graphite, and its properties can depend on the nature of stacking in the graphene structures. In this study, GO was prepared...
