▎ 摘　　要

To improve interfacial interaction with the epoxy resin, carbon nanotube (CNT) and graphene nanoplatelet (GNP) are fluorinated. A surface-chemical property of the surface-treated CNT and GNP has been analyzed by X-ray photoelectron microscopy (XPS). Then the mechanical properties and thermal stabilities of composites which are reinforced by them are also evaluated. The mechanical properties of CNT/GNP reinforced epoxy composites are comparatively higher than those of epoxy composites reinforced with CNT only. These results are attributed to a size effect resulted from the network structures due to different aspect ratios of reinforcement. The tensile, impact strength, and thermal stability of the composites including fluorinated CNT and GNP are remarkably increased by 101, 69, and 130% compared to those of neat epoxy, respectively. These results are attributed to the synergy effect of the size effect and improvement of interfacial interaction between surface-treated reinforcements and epoxy resin.
