Preparation method of polyaniline conductive film

Abstract

The invention discloses a preparation method of a polyaniline conductive film. Specific preparation steps comprise: 1) preparation of an aqueous solution of an initiator; 2) preparation of a compositesilane solution; 3) preparation of organic modified calcium carbonate; 4) preparation of a wax solvent; 5) preparation of a polyaniline solution; 6) preparation of modified polyaniline; and 7) preparation of the polyaniline conductive film. During the polymerization process of aniline, an acid doping agent is introduced, thus effectively enhancing conducting stability of the polyaniline product.Meanwhile, by adding t-butyl, storage stability of the film can be enhanced.

Description

technical field [0001] The invention belongs to the field of film preparation, and in particular relates to a preparation method of polyaniline conductive film. Background technique [0002] Among the conductive polymers that have been discovered so far, polyaniline has many advantages such as simple synthesis, low price, adjustable conductivity, and good environmental stability, especially in the fields of metal corrosion protection, electrostatic discharge, and electromagnetic interference shielding. The prospect of large-scale application has become the most widely studied conductive polymer material; however, in order to further improve the conductive properties of polyaniline and expand its application fields, it is often blended with conductive inorganic particles at present. Improve the conductivity, but due to the poor compatibility of inorganic particles and polyaniline, the stability of the finished product will also be poor, especially when it is made into a compo...

The prospect of large-scale application has become the most widely studied conductive polymer material; however, in order to further improve the conductive properties of polyaniline and increase its application fields, it is often blended with conductive inorganic particles at present, although it can be Improve the conductivity, but due to the poor compatibility of inorganic particles and polyaniline, it will also cause poor stability of the finished product, especially when it is made into a composite film, it is more likely to cause poor uniformity and stability of the film and reduce the quality of the conductive film
