Synthesis, infrared and microwave absorbing properties of (BaFe12O19+BaTiO3)/polyaniline composite

► The specimens were synthesized by in situ polymerization to be a microwave and infrared absorber. ► The composites exhibit good absorption performances over a broad band range in 2-40 GHz band. ► A significant thermal extinction was obtained by adding polyaniline in BaFe12O19+BaTiO3 blend.
