Abstract

Graphene and its composites are rising high technological materials. However, several

challenges, including agglomeration and weak interfacial interactions, still need to be

addressed. These issues can be solved by selecting proper the dispersion method and the

functionalization of graphene. In this work, the mechanical properties of the nanocomposites

composed of 0.1 wt% functionalized graphenes (f-GNFs) and epoxy resin under the tensile load

are studied. The graphene is functionalized with Triton X-100 surfactant and mechanically

dispersed by using three roll milling (3RM). Compared to the neat epoxy, the f-GNFs reinforced

nanocomposites are less stiff (-7.25%), more ductile (+30.82%), and stronger (+19.03%) under

quasi-static tensile testing.
