Recently, electromagnetic interference (EMI) shielding is considered an important issue in our daily life. Carbon nanomaterials such as graphene and multi-walled carbon nanotube (MWCNT) are considered promising materials for the development of EMI shielding due to their excellent electronic and mechanical properties. However, the EMI shielding of polymer nanocomposites using the sole reduced graphene oxide(rGO) are relatively low performance. Fortunately, lots of researches have proved that rGO sheets integrated with other 1D or 2D nanomaterials show further enhancement in EMI shielding. In this study, rGO/MWCNT hybrid fillers were prepared using covalent bonding. rGO/MWCNT hybrid fillers form bridge via amide bonds. With different content of hybrid fillers, epoxy composites were fabricated by casting method. The morphology and EMI shielding of the hybrid fillers according to various ratio were investigated. |
