Abstract

To improve the mechanical and damping properties of epoxy, a kind of solvent-free nanofluids, which contain a multi-core of graphene oxide (GO) and Fe₃O₄ nanocrystalline, was designed. Various analysis technologies were employed to characterize the morphology, chemical structure of the nanofluids. It exhibited liquid-like behavior at room temperature, and good dispersion in solvent and epoxy. The study on the mechanical and damping properties of the nanofluids/epoxy nanocomposite indicated that the nanofluids can adjust the interface between GO and epoxy matrix, and it enhanced the bending strength, impact strength and loss factor of epoxy by 18.65%, 41.95% and 24.74% at the 4.5 wt% content, respectively.
