To improve the mechanical properties of epoxy composites, multiwalled carbon nanotubes (MWCNTs) were oxyfluorinated and used as reinforcement in an epoxy matrix. A comparison of various oxyfluorinated MWCNTs and neat epoxy revealed that the tensile strength of the epoxy composites with oxyfluorinated MWCNTs increased by approximately 24%. The maximum impact strength of these epoxy composites were improved by 43% compared to that of neat epoxy. The electromagnetic interference shielding efficiency (EMI-SE) of the epoxy composites with oxyfluorinated MWCNTs was enhanced with the increasing oxygen concentration during the oxyfluorination. The composites resulted in the maximum EMI-SE increase of 18% compared to that of the neat epoxy. These results were attributed to the oxyfluorination effects of MWCNTs, which form an interface with stronger adhesion as a consequence of the presence of oxygen and fluorine functional groups on the surface of the MWCNTs.
