Inorganic particle modified magnetic composite material and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention mainly relates to the field of composite materials, in particular to an inorganic particle modified magnetic composite material and a preparation method thereof. Background technique [0002] There are two main methods of synthesizing conductive polymers; one is chemical polymerization, in which conjugated polymers are obtained by oxidizing monomers with oxidants or coupling metal-organic compounds; the other is electrochemical polymerization, in which Under the action of an electric field, a solution containing monomers is electrolyzed to obtain conjugated polymers on the electrode surface; [0003] The original starting point of the composite modification of conductive polymers is to overcome the disadvantages of poor processability, but through this approach, a variety of functional composite materials can also be obtained, thereby expanding its application fields. These functional materials can be widely used in the fields of conduct...
