제목 Evaluation of thermal and mechanical properties of epoxy composite reinforced with fluorinated carbon nanotube and graphene nano-platelet
초록 Fluorinated carbon nanotube(CNT) and graphene nanoplatelet(GNP) were used as reinforcements to improve the mechanical properties of epoxy composite. The effect of fluorination on the surface of CNT and GNP was investigated by x-ray photoelectron spectroscopy(XPS). Thermal stabilities and mechanical properties were analyzed by TGA and tensile and impact strength test. CNT/GNP reinforced epoxy composite exhibited higher strength than CNT reinforced. This result was due to the size effect as the two reinforcements had different aspect ratio. The tensile and impact strength of the composites, which were reinforced with surface fluorinated CNT and GNP, were increased approximately 101 % and 69 % compared to those of neat epoxy. Also, thermal stability of the composites was improved 130 % than that of neat epoxy. These results are due to the synergy effect composed with size effect of reinforcements according to the different aspect ratio and improvement of dispersion in epoxy resin.
