- Abstract
Abstract: The present work has the objective of fabricating graphene oxide (GO) and amine‐functionalized graphene oxide (F‐GO) reinforced epoxy composites using the casting method. Epoxy resin was dispersed separately with GO (0.5 wt%) and F‐GO (0.5 and 1 wt%), and then the epoxy resin mixture cured with triethylenetetraamine at room temperature. The synthesized GO and F‐GO were characterized by FT‐IR and Raman spectroscopy. The interfacial interaction of Si in the composite was studied by XPS. The formation of GO and F‐GO was confirmed by XRD. The tensile and flexural strength composites were measured using the UTM. The thermal behavior and dynamic mechanical behavior were examined by TGA and DMA. The surface morphology and dielectrical properties were analyzed by SEM, TEM, and impedance analyses. The results obtained from epoxy/F‐GO (0.5 wt%) composite revealed higher mechanical and thermal properties than neat epoxy and epoxy/GO composites.
