Abstract

The invention discloses a polypyrrole sol conductive film which is prepared from the following raw materials in parts by weight: 3-4 parts of triethylamine, 27-30 parts of pyrrole, 0.1-0.2 part of 2-mercapto benzimidazole, 0.4-1 part of etidronic acid, 0.7-1 part of dicumyl peroxide, 2-5 parts of acrylic polyoxyethylene glycols, 1-2 parts of polydimethylsiloxane, 1-2 parts of acetylene black, 5-7parts of palm wax, 2-3 parts of ammonium polyphosphate, 100-140 parts of dimethyl formamide and 17-20 parts of isopropyl alcohol. According to the invention, the conductive carbon black is dispersed into dimethyl formamide in advance, so that the effective mixing combination of carbon black and polymer is realized and the electrical conductivity and mechanical properties of the end products are further promoted.

Description

technical field [0001] The invention belongs to the field of films, and in particular relates to a polypyrrole sol conductive film and a preparation method thereof. Background technique [0002] Conductive thin film is a very important optoelectronic material. It has the characteristics of low resistance and is widely used in various optoelectronic materials such as solar cells, electrode materials, and displays. At present, inorganic oxide thin films are widely used. Good chemical resistance, low resistivity, good chemical temperature resistance, but as an inorganic filler, its film has high brittleness, poor toughness, and high synthesis temperature, all of which limit their further development. Therefore, polymers gradually appear in the market Conductive materials, including polyaniline, polypyridine, etc.; [0003] Polypyrrole is a heterocyclic conjugated conductive polymer, usually an amorphous black solid, which uses pyrrole as a monomer to make a conductive film thr...
