Abstract

The invention discloses a conductive polyaniline polypyrrole composite membrane and a preparation method thereof. Aniline and pyrrole monomers are dissolved into an organic solvent, a supporting electrolyte is dissolved into water, thus two solutions are respectively prepared, the two solutions are transferred into a reactor in steps, so as to form a liquid-liquid interface, and a working electrode is directly inserted in the liquid-liquid interface, an auxiliary electrode and a reference electrode are placed into the supporting electrode solution, and electrochemical polymerization is carried out by electrochemical means. The polymer prepared by the method of the invention can spread out and grow on the interface, the polymerization product is proved to have good conductivity, and the polymerization product can be applied to a super capacitor, the anode material and cathode material of a battery, electromagnetic shielding and the like.

Description

technical field [0001] The invention relates to a method for preparing a conductive polymer, in particular to a method for preparing a conductive polyaniline-polypyrrole composite film on a large scale, and belongs to the field of polymer materials. Background technique [0002] Conductive polymers, also known as conductive polymers, refer to polymers whose electrical conductivity is within the range of semiconductors and conductors through doping and other means. This type of polymer backbone contains alternating single and double bonds, thus forming a large conjugated π system. The flow of π electrons creates the possibility of conduction. Common conductive polymers are: polyacetylene, polythiophene, polyaniline, polyaniline, polyphenylene, polyphenylene vinylene and polyacetylene, etc. Conductive polymers not only have high electrical conductivity, but also have photoconductive properties, nonlinear optical properties and magnetic properties, which not only have importa...
