In situ growth of BaTiO3 nanotube on the surface of reduced graphene oxide: A lightweight electromagnetic absorber

Abstract Special materials for electromagnetic absorber (EMA) and stealth camouflage techniques are desired due to their widespread applications in the military field. In this paper, BaTiO 3 /reduced graphene oxide (RGO) composites via hydrothermal process were prepared. BaTiO 3 nanotube has unique features: single crystalline, high aspect ratio and uniform distribution on RGO nanosheet. Compared with pure BaTiO 3 nanowire, BaTiO 3 /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 BaTiO 3 /RGO composites could be used as promising materials for EMA and broad absorption properties.
