Mechanical and Thermal Properties of Epoxy Resin Nanocomposites Reinforced with Graphene Oxide

A facile approach to fabricate graphene oxide (GO) reinforced epoxy resin nanocomposites was developed by transferring GO from water to acetone. Three-point bending test, impact test, dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA) were used to investigate the mechanical and thermal properties of the nanocomposites. The results showed that significant improvements in flexural strength, flexural modulus, impact strength, and storage modulus were achieved when incorporating similar to 1 wt% of graphene oxide. The TGA analysis indicated that the introduction of GO has not demonstrated obvious effect on the thermal stability.
