Heat-resistant graphene conductive thin film and preparation method thereof

Abstract

The invention discloses a heat-resistant graphene conductive thin film. The heat-resistant graphene conductive thin film is prepared from the following raw materials in parts by weight: 10 to 14 partsof graphene, 1 to 2 parts of diethylene glycol dibenzoate, 0.8 to 1 part of alkanolamide, 1 to 2 parts of silane coupling agent kh550, 2 to 3 parts of barium stearate, 0.1 to 0.2 part of stannous sulfide, 5 to 7 parts of heat-resistant polyethylene wax, 0.1 to 0.2 part of alkylphenol polyoxyethylene, 60 to 70 parts of polyaniline, 1 to 2 parts of ammonium polyphosphate, 3 to 4 parts of aluminiumdihydrogen phosphate, and 2 to 3 parts of triethanolamine. The heat-resistant graphene conductive thin film has the advantages that by adding the aluminium dihydrogen phosphate, calcium acetylacetonate and the like, the heat-resistant stability of the finished thin film is improved; by adding the aluminium dihydrogen phosphate, the viscosity between the raw materials can be enhanced in the calendering and filming process, thereby further improving the uniform stability of filming.

AI Technical Summary

Problems solved by technology

Polyaniline has been widely studied and applied because of its easy-to-obtain raw materials, simple synthesis process, and good chemical and environmental stability; polyaniline film is a conductive film, which is widely used in solar cells, electrode materials, displays, etc. Among various optoelectronic materials, however, at present, commercially available polyaniline films have poor heat resistance stability, and in order to improve their heat resistance performance, high heat resistant inorganic fillers are often added therein, because the compatibility between inorganic fillers and polyaniline is poor , which will easily reduce the mechanical stability of the film
