Abstract

The invention discloses an electric synthesizing method of polyaniline. The electric synthesizing method is characterized by comprising the following steps of S1. ultrasonically washing conducting glass for 15min respectively in distilled water, absolute ethyl alcohol, acetone, absolute ethyl alcohol and distilled water so as to remove the surface impurities, and naturally drying the conducting glass; S2. placing the conducting glass into an electrolytic tank, scanning the conducting glass at a constant scanning speed by utilizing a cycling voltammetry, and adopting the mixed solution of 0.5mol/L HCL and 0.5mol/L aniline as electrolyte; S3, rapidly transferring a working electrode aggregating the polyaniline into the distilled water, and washing the working electrode with the distilled water to remove the residual acid radical ions and aniline monomers; and S4. standing the polyaniline working electrode under the condition of 10 DEG C for 24h to be dried. The electric synthesizing method has the advantages that the synthesized polyaniline film is stable in structure, and the good electric performance can be maintained, and the instability defect of the electrode caused by the adhesion can be overcome.

Description

technical field [0001] The invention belongs to the technical field of conductive polymers, and relates to an electrosynthesis method of polyaniline. Background technique [0002] Polyaniline is a commonly used conductive polymer material, which has the advantages of low cost, high chemical stability, and high conductivity. It is the most commercially valuable of many conductive polymers. New properties and applications can be brought to polyaniline by introducing substituents on polyaniline macromolecular chains or introducing different anions by protonic acid doping. At present, polyaniline has begun industrial production and has been applied in practice. [0003] Completely reduced polyaniline (Leucoemeraldine base) is non-conductive and white, and the repeating units in the main chain are not conjugated; after oxidation doping, Emeraldine base is obtained, which is blue and non-conductive; after acid doping, Emeraldine salt is obtained , green, conductive; if the Emera...
