▎ 摘　　要

NOVELTY - A polyaniline/graphene oxide/ferroferric oxide composite absorbing material comprises film-forming material and electromagnetic wave absorbent. The film-forming material is formed using paraffin wax. The electromagnetic wave absorbent is formed using polyaniline/graphene oxide/ferroferric oxide ternary complex. USE - Polyaniline/graphene oxide/ferroferric oxide composite absorbing material is used for microwave absorption and electromagnetic shielding. ADVANTAGE - The polyaniline/graphene oxide/ferroferric oxide composite absorbing material has excellent electromagnetic wave absorbing characteristics and strength, and is prepared by economical and simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of polyaniline/graphene oxide/ferroferric oxide composite wave-absorbing material, which involves mixing polyaniline/graphene oxide/ferroferric oxide ternary compound and paraffin wax, heating, and naturally cooling. The polyaniline/graphene oxide/ferroferric oxide ternary complex is obtained by adding iron(III) chloride and ferroferric oxide in solution containing aniline and hydrochloric acid, reacting, adding graphene oxide, dripping ammonium sulfate solution, reacting, filtering, washing using deionized water, and vacuum drying. The graphene oxide is obtained by adding natural crystalline flake graphite and sodium nitrate in concentrated sulfuric acid, mixing, adding potassium permanganate, stirring, reacting, then adding deionized water, stirring, cooling to room temperature, adding hydrogen peroxide, centrifuging, washing, and vacuum drying. The ferroferric oxide are obtained by adding iron(II) chloride tetrahydrate and iron(III) chloride hexahydrate to 10 mL deionized water, stirring, dissolving, adding ammonium hydroxide having concentration of 28 wt.%, reacting, centrifuging, washing, and vacuum drying.
