▎ 摘 要
Herein, amphiphilic graphene oxide (GO) was used as the "surfactant" to directly disperse pristine multi-walled carbon nanotubes (MWCNTs) in aqueous dispersions and the reduced graphene oxide/multiwalled carbon nanotubes/nickel ferrite (RGO/MWCNTs/NiFe2O4) ternary nanocomposites were further synthesized by a facile one-pot hydrothermal strategy. The structure, compositions, micromorphology and electromagnetic parameters of the ternary nanocomposites were investigated by various analytical techniques. Experimental results revealed that the ternary nanocomposites exhibited the enhanced electromagnetic wave (EMW) absorption performance compared with the binary nanocomposite and single NiFe2O4. The minimum reflection loss (RLmin) reached -50.2 dB with a thin thickness of 1.4 mm and effective absorption bandwidth (EAB, RL
