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

Abstract Graphene oxide (GO) is a versatile material with inherent unique properties that can be used in wide range of applications. GO produced from graphitic materials including graphite, and its depend on the nature stacking graphene structures. In this study, was prepared pitch-based graphite fibers via modified Hummer’s method subsequently incorporated into an epoxy matrix to obtain graphene-loaded nanocomposites (EP/GO). Presented experimental results revealed addition 0.6 wt% yielded ∼110% increase fracture toughness. The corresponding energies as well flexural strengths modulus exhibited similar trends thermophysical EP/GO, further demonstrate reinforcing effectiveness GO, were also observed. Collectively, these indicate investigated study viable reinforcement candidate develop next-generation multifunctional properties.
