▎ 摘　　要

NOVELTY - Polyaniline-barium ferrite-graphene electromagnetic shielding material comprises 56-75 pts. wt. cobalt-titanium co-doped barium ferrite, 8-15 pts. wt. three-dimensional porous graphene, 5-9 pts. wt. aniline, and 12-20 pts. wt. ammonium persulfate. USE - Polyaniline-barium ferrite-graphene electromagnetic shielding material. ADVANTAGE - The polyaniline-barium ferrite-graphene electromagnetic shielding material has rich pore structure, higher dielectric constant and saturation magnetization, enhances the permeability and magnetic loss performance of barium ferrite, graphene and polyaniline, the charge transfer process and interface polarization effect of the material, and improves the dielectric loss performance of the material, has dielectric loss and steric reflection effect, good impedance matching performance, shows excellent electromagnetic shielding and wave absorption performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing polyaniline-barium ferrite-graphene electromagnetic shielding material, which involves adding porous nano-cobalt-titanium co-doped barium ferrite and three-dimensional porous graphene into distilled water, ultrasonically dispersing uniformly, adding hydrochloric acid to adjust the pH of the solution to 2-4, then adding aniline and ammonium persulfate, reacting at 0-5 degrees C for 10-18 hours, removing the solvent, washing and drying to prepare polyaniline-barium ferrite-graphene electromagnetic shielding material.
