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

Abstract

The invention discloses a heat-resistant graphene conductive film, which is composed of the following raw materials by weight: 10-14 parts of graphene, 1-2 parts of diethylene glycol dibenzoate, 0.8-1part of alkanolamide, 1-2 parts of silane coupling agent kh550, 2-3 parts of barium stearate, 0.1-0.2 part of stannous sulfide, 5-7 parts of heat-resistant polyethylene wax, 0.1-0.2 part of alkylphenol ethoxylate, 60-70 parts of polyaniline, 1-2 parts of ammonium polyphosphate, 3-4 parts of aluminum dihydrogen phosphate, and 2-3 parts of triethanolamine. The aluminum dihydrogen phosphate, calciumacetylacetonate and the like added by the invention may improve the heat stability of the finished film, and the aluminum dihydrogen phosphate may also enhance the viscosity between the raw materialsin the cast film forming process, thereby further improving the uniform stability of the film formation.
