Reduced graphene oxide (rGO) and metal nitride/carbides (MXene) are promising research topics, and rGO and MXene are applied to electromagnetic shielding materials due to their lightweight and excellent electrical properties. In this study, the rGO-MXene foam was prepared by adding a surfactant to the rGO-MXene solution. After reacting with various surfactants (ascorbic acid, ethylenediamine, sodium dodecyl benzenesulfonate, sodium alginate, cetyltrimethylammonium bromide, etc.), the rGO-MXene foam was prepared through freeze-drying and reduced to HI. The rGO-MXene foam was impregnated into an epoxy solution to prepare a foam-type rGO-MXene/epoxy composite. The arrangement of the rGO-MXene sheet was different according to the type of surfactant, and EMI SE was measured according to each type. The synergistic effect of rGO-MXene foams was studied by comparing different weight ratios.
