▎ 摘　　要

Special materials for electromagnetic absorber (EMA) and stealth camouflage techniques are desired due to their widespread applications in the military field. In this paper, BaTiO3/reduced graphene oxide (RGO) composites via hydrothermal process were prepared. BaTiO3 nanotube has unique features: single crystalline, high aspect ratio and uniform distribution on RGO nanosheet. Compared with pure BaTiO3 nanowire, BaTiO3/RGO composites exhibited good absorption properties. The maximum reflection loss (RL) of BaTiO3/reduced graphene oxide (RGO) composites is about of -44.9 dB, and they exhibited an effective electromagnetic absorption bandwidth of 5.4 GHz with the thickness of 2.5 mm BaTiO3/RGO composites could be used as promising materials for EMA and broad absorption properties.
