Abstract

The invention discloses a preparation method of a heat-resistant conductive polyaniline film. The method comprises the following preparation steps: (1) preparing an aqueous solution of ammonium persulfate; (2) preparing a phosphorous doped polymer emulsion; (3) preparing a heat-resistant polymer; and (4) preparing the heat-resistant conductive polyaniline film. According to the preparation methoddisclosed by the invention, phosphorus trichloride serves as a modifier, an aniline monomer is doped after hydrolysis, the polyaniline is endowed with excellent conductivity and then mixed and esterified with bisphenol A, the obtained bisphenol A ester has excellent heat-resistant stability, and the heat-resistant strength of the finished film is improved. The film disclosed by the invention is excellent in conductivity stability, high in mechanical strength, excellent in heat-resistant stability and excellent in comprehensive property.

Description

technical field [0001] The invention belongs to the field of films, and in particular relates to a preparation method of a heat-resistant polyaniline conductive film. 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 in fields such as biosensors, anti-corrosion materials, and wave-absorbing materials. However, the low conductivity of polyaniline, post-processing, and poor stability have greatly affected its popularization and application. [0003] At the same time, with the vigorous development of polyaniline films, new requirements have been put forward for the mechanical strength and heat resistance of the films to adapt to different working environments. ...
