The invention discloses an inorganic particle modified magnetic composite material. The composite material is composed of, by weight, 3-4 parts of aluminum isopropoxide, 100-130 parts of ferric chloride hexahydrate, 60-69 parts of ferrous chloride tetrahydrate, 0.1-0.2 part of silane coupling agent kh560, 0.3-0.5 part of tea saponin, 40-54 parts of ammonium persulfate, 40-57 parts of pyrrole, 0.4-0.6 part of ethyl cellulose, 3-6 parts of tetraethoxysilane, 1-2 parts of polymaleic anhydride, 0.04-0.1 part of palm wax, 0.06-0.1 part of polysorbate, 0.4-1 part of polyacrylamide, 2-3 parts of polyethylene glycol, 0.1-0.16 part of dipotassium glycyrrhizinate, 0.7-1 part of calcium acetylacetonate, 50-60 parts of alcohol solution of 70-75% and 60-70 parts of anhydrous alcohol. By adding the composite material high in dispersity into polypyrrole, compactness of polypyrrole can be improved to certain extent, so that electroconductivity and environmental stability of the composite material are improved. The inorganic particle modified magnetic composite material has both electrical performance and magnetic performance and has important application value in the field of stealth technology and electromagnetic shielding.
