Preparation method of polyaniline/polypropylene composite material

Abstract

The invention discloses a preparation method of a polyaniline / polypropylene composite material. The method is characterized by comprising the following steps: dispersing and dissolving ammonium persulfate into water, to obtain an ammonium sulfate solution; adding aniline to the ammonium sulfate solution and stirring for reaction for 6-12 hours, thus obtaining a polyaniline solution after reaction is ended; carrying out suction filtration on the polyaniline solution, then adding stearic acid which is dissolved by a mixed solution of absolute ethyl alcohol and carbon tetrachloride to the polyaniline solution to perform doping treatment; carrying out suction filtration on the polyaniline subjected to doping treatment; drying and grinding into polyaniline powder like flour; and evenly mixing polyaniline with polypropylene, and plasticizing into the polyaniline / polypropylene composite material by virtue of an open rubber mixing mill, wherein the mass percent of polyaniline in the polyaniline / polypropylene composite material is 2-10%. The performances of the polyaniline / polypropylene composite material accord with the use requirements under different conditions, and the polyaniline / polypropylene composite material has the advantages of simple process and high product polymerization degree.

Description

technical field [0001] The invention relates to a preparation method of an electrode material, in particular to a preparation method of a polyaniline / polypropylene composite material. Background technique [0002] Conductive polymers, also known as conductive polymers, refer to compounds with a very large degree of polymerization, whose molecules are linked together by many small repeating structural units or monomers through covalent bonds, and at both ends of the compound When a voltage is applied, a directed movement of electrons occurs in the material. At present, the conductive polymers that have been studied more include polypyrrole, polythiophene, poly-p-phenylene, poly-p-toluene vinylene, and polyaniline. [0003] Among many conductive polymer materials, polyaniline has broad application prospects in practical application because of its cheap raw materials, simple synthesis process, good physical and chemical stability, high electrical conductivity and excellent ele...
