Gelled polyaniline conductive film and preparation method thereof

Abstract

The invention discloses a gelled polyaniline conductive thin film, which is prepared from the following raw materials in parts by weight: 2-3 parts of sodium persulfate, 0.7-1 part of dialkyl p-diphenol, 4-6 parts of methacrylic acid, 3-5 parts of rubber powder, 0.1-0.2 part of p-toluenesulfonic acid, 5-7 parts of epoxypropanol, 90-100 parts of aniline, 2-4 parts of diethylenetriamine and 6-9 parts of graphene oxide. According to the invention, diethylenetriamine is adopted to treat graphene oxide, then the treated graphene oxide is blended with a rubber powder modified polyaniline solution, and epoxy crosslinking is promoted at a high temperature, so that the dispersion performance of rubber powder and graphene among polyaniline is realized, the compatibility among the raw materials is improved, and the mechanical and conductive properties of the finished product film are further improved.

Description

technical field [0001] The invention belongs to the field of films, and in particular relates to a gelled polyaniline conductive film and a preparation method thereof. Background technique [0002] As one of the conductive polymer materials, polyaniline is considered to be the structural conductive polymer with the most commercial application value because of its good chemical stability, good weather resistance, cheap and easy-to-obtain raw materials, simple synthesis method, and electrical conductivity. There is a huge market demand for biosensors, anti-corrosion materials, and wave-absorbing materials, but the low conductivity of polyaniline, post-processing, and poor stability have greatly affected its popularization and application; [0003] At present, with the increasing application of polyaniline film, its safety is the focus of attention.

[0003] At present, with the increasing application of polyaniline film, its safety is the focus of attention. However, in order to further improve the fire performance of polyaniline, flame retardant inorganic fillers are often introduced into it. However, due to the poor compatibility of inorganic particles and polyaniline, the stability of the finished product will also be poor
