Problems solved by technology

However, its conductivity, energy density, catalytic activity, electrochromism, and energy conversion are all affected by pH, which limits its application to some extent.
This is because at pH > 4, polyaniline almost loses its electrochemical activity, and the conductivity becomes very low

Embodiment Construction

[0012] 1. Raw materials:

[0013] Aniline, o-aminophenol, sulfuric acid.

[0014] The aniline was distilled under reduced pressure and stored in a refrigerator at 4°C for later use.

[0015] 2. Preparation of electrolyte:

[0016] Add aniline and o-aminophenol into sulfuric acid aqueous solution, stir until homogeneous with an electromagnetic stirrer, and make the aniline concentration 0.1-0.3moldm -3 , the concentration of anthranilic acid is 0.005~0.015moldm -3 , the concentration of sulfuric acid is 0.4~1.2moldm -3 .

[0017] 3. Electrolytic cell preparation:

[0018] The electrolytic cell adopts a three-electrode system consisting of two platinum sheets and a saturated calomel electrode (SCE) reference electrode.

[0019] The two platinum sheets were pretreated with a mixed solution of potassium dichromate and sulfuric acid before electrolysis.

[0020] 4. Electrolytic synthesis:

[0021] The prepared solution was added to the electrolyte and electrolyzed by cyclic...

Abstract

The invention relates to a technical field of electric high polymer, in the electrolytic cell composed of Pt electrode, electrolyzing aniline, o-aminophenol and vitriol to obtain electrolytic resultant, then washing the resultant by HCl water solution to dry, so as to obtain the copolymer of aniline and o-aminophenol, which not only has the excellent property of aniline but also its activity in acidic solution slightly higher than polyaniline's, and still maintains very high electrochemical activity in pH 9.6 sodium sulfate solution, and when pH rises from 5.0 to 9.6, its electrochemical activity only decreases by 29%. Besides, when it is at high pH, it still has wider applied potential range {-0.2-0.5V(vs, SCE)} and conductivity 0.5-1.2Scm-1.

Description

technical field [0001] The invention relates to the technical field of a high polymer with conductive properties. Background technique [0002] Among conductive polymers, polyaniline is the most attractive. This is because polyaniline has high electrical conductivity, redox reversibility, the color of the film can change rapidly with potential, and it is very stable in aqueous solution and air. These properties are suitable for applications in storage batteries, electrocatalysis, electrochromism, and photoelectric conversion. However, its conductivity, energy density, catalytic activity, electrochromism, and energy conversion are all affected by pH, which limits its application to some extent. This is because at pH>4, polyaniline almost loses its electrochemical activity, and the conductivity also becomes very low. Contents of the invention [0003] The purpose of the present invention is to invent a novel conductive polymer with high electrochemical activity and con...
