Abstract

The present invention relates to a chemical oxidation synthesis method of conductive high polymer-benzenamine and m-aminophenol copolymer, belonging to the field of synthesis technology of high polymer with electrical conductivity. Said method includes the following steps: in a strong acid solution using ammonium persulfate to simultaneously oxidate benzenamine and m-aminophenol to form copolymer, making reaction for 8-12 h under the condition of stirring and normal temperature, then using hydrochloric acid aqeous solution whose pH value is 3 to wash the above-mentioned product, then vacuum drying at 70-90 deg.C so as to obtain the invented conductive copolymer.

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. In addition, polyaniline is easy to synthesize and low in cost. However, these properties are all affected by the pH value, which limits its application to a certain extent, because when the pH>4, polyaniline almost completely loses its electrochemical activity, and its conductivity becomes very low. Low. Therefore, the pH characteristic of polyaniline is a key factor controlling the properties and applications of polyaniline. The electrochemica...
