Improved mechanical and electromagnetic interference shielding properties of epoxy composite by introducing of oxyfluorinated MWCNTs |
| 초록 |
To improve the mechanical properties and electromagnetic interference shielding effect (EMI-SE), multi-walled 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 and impact strength of the oxyfluorinated MWCNTs/epoxy composites increased by as much as 24% and 43%, respectively. The EMI-SE of the oxyfluorinated MWCNTs/epoxy composites was enhanced; the highest oxygen concentration used in oxyfluorination resulted in the maximum EMI-SE increase. These results were explained by the oxyfluorination effects of MWCNTs, which increases the compatibility with the epoxy resin due to the formation of an interface with stronger adhesion as a consequence of the presence of oxygen and fluorine functional groups on the MWCNT’ surface. |
