摘要: Ba0.9La0.1Fe11.9Ni0.1O19 nanoparticles were prepared by a co-precipitation method, and Ba0.9La0.1Fe11.9Ni0.1O19/reduced graphene oxide/polyaniline ternary nanocomposites (BF/RGO/PANI) in situ polymerization. Microwave reflection loss, the permittivity permeability of BF/RGO/PANI investigated frequency range 2–18 GHz. The samples possessed excellent electromagnetic wave-absorbing performances, optimal impedance matching was found. minimum loss reached −49.1 dB near 14.08 GHz with thickness 1.9 mm its absorption bandwidth below −10 ranged from 12.4–16.72 4.32 Our study illustrates that as-prepared are promising candidates for use materials.
