Preparation and microwave adsorption properties of core-shell structured barium titanate/polyaniline composite

► Nano-BaTiO3 particles were prepared by the sol-gel method. ► The core-shell structured BaTiO3/polyaniline composites were synthesized by in-situ polymerization. ► The effect of the mass ratio of BaTiO3/PANI on the microwave loss properties of the composites was investigated.
