초록

In this study, graphene oxide(GO) was synthesized using Hummer's method. Then, silica nanoparticles-coated GO($SiO_2/GO$) were synthesized by in-situ sol-gel synthesis under a water-alcohol mixture at room temperature ($25^{\circ}C$). GO and $SiO_2$ were used as additives in epoxy resin nanocomposites that were prepared by mixing Tetraglycidyl diamino diphenyl methane(TGDDM) and hardner(M-DEA+M-MIPA). Fourier transform infrared(FT-IR) spectra and X-ray photoelectron spectroscopy (XPS) of $SiO_2/GO$ were conducted. Thermal and mechanical properties of epoxy resin nanocomposites were confirmed by analytical methods such as TG-DTA, DMA, fracture toughness, and tensile strength. The fracture surfaces of epoxy resin nanocomposites with different contents of GO and $SiO_2/GO$ were observed by a Scanning Electron Microscope(SEM). The mechanism for mechanical properties of epoxy resin nanocomposites was analyzed by modeling of nanocomposites with different GO and $SiO_2$ weights. Due to the GO, both the heat resistance and the glass transition temperature of the epoxy resin nanocomposites were improved. Interestingly, when 0.1 wt% of GO was added to the epoxy resin/hardener mixture, the mechanical properties increased compared to that of neat epoxy resin. There results were caused by an aggregation between the GO and $GO/SiO_2$. Based on the analysis of the mechanical properties of $SiO_2$ addition, buckling analysis was performed and the critical load and buckling shape were confirmed.
