Problems solved by technology

However, the above documents and patents only focus on improving the solubility of polyaniline, while ignoring the mechanical properties of polyaniline materials. The resulting polyaniline coating has low mechanical strength and poor adhesion, and can be easily wiped off with fingers.

Embodiment 1

[0031] Place the three-necked flask in a water bath at 5°C, add a certain amount of macromolecular protonic acid dodecylsulfonic acid to 150.0ml ethanol, adjust the pH value to about 0.5, and then add monomer A7.3g m- (5-Hydroxybutylthio)aniline, monomer B 10.0 g m-(3-trimethoxysilylethylthio)aniline. Dissolve 9.9g of the oxidant potassium persulfate in absolute ethanol, and slowly add it dropwise to the three-necked flask under nitrogen protection and stirring. The dropwise addition is completed within half an hour. React at room temperature for 15 hours. Suction filtration was performed after the reaction was completed, and then dried at room temperature for 2 hours to obtain conductive polyaniline. The obtained conductive polyaniline was dissolved in a mixed solvent of xylene:butanol=60:40, sprayed and dried at 60° C. to form a film.

Embodiment 2

[0033] Place the three-necked flask in a 5°C water bath, add a certain amount of macromolecular protonic acid octylsulfonic acid to 150.0ml n-propanol to adjust the pH value to about 0.5, and then add monomer A9.7g m-(5 -Hydroxybutylthio)aniline, monomer B 6.7 g m-(2-dimethoxyethoxysilylethylthio)aniline. Dissolve 19.7g of oxidant potassium persulfate in anhydrous n-propanol, and slowly add it dropwise to a three-necked flask under nitrogen protection and stirring. The dropwise addition is completed within half an hour. After the dropwise addition, keep it at 5°C for 4 hours. , reacted at room temperature for 15 hours. Suction filtration was performed after the reaction was completed, and then vacuum-dried at room temperature for 2 hours to obtain conductive polyaniline. The obtained conductive polyaniline was dissolved in a mixed solvent of xylene:butanol=60:40, sprayed to form a film, and then dried at 60° C. to form a film.

Embodiment 3

[0035] Place the three-necked flask in an ice-water bath, add a certain amount of macromolecular protonic acid heptanesulfonic acid in 150.0ml of isopropanol to adjust the pH value to about 0.5, and then add monomer A9.4g m-(9 -Hydroxyoctylthio)aniline, monomer B 10.5g m-(4-dimethoxyethoxysilylbutylthio)aniline. Dissolve 19.8g of the oxidant potassium persulfate in anhydrous isopropanol, and slowly add it dropwise to the three-necked flask under nitrogen protection and stirring. The dropwise addition is completed within half an hour. After the dropwise addition, keep it at 0°C for 4 hours. , reacted at room temperature for 20 hours. Suction filtration was performed after the reaction was completed, and the filter residue obtained by suction filtration was vacuum-dried at room temperature for 5 hours to obtain conductive polyaniline. The obtained polyaniline was dissolved in a mixed solvent of xylene:butanol=60:40, sprayed and dried at 60°C to form a film.

Abstract

A electrically conductive polyphenylamine with high solubility, mechanical performance and adhesion is prepared from the hydroxyalkylthio ring substituted phenylamine and the siloxyalkylthio ring substituted phenylamine through copolymerizing under existence of oxidant and long-chain alkylprotonic acid.

Description

technical field [0001] The invention relates to a preparation technology of a conductive polymer material, in particular to a preparation technology of a conductive polyaniline. Background technique [0002] Compared with other conductive polymer materials with long-chain conjugated structure, polyaniline has low raw material price, simple synthesis process, and special doping mechanism, which has good application prospects. The application based on the photoelectric properties of polyaniline is mainly to replace traditional metal conductive materials, flat display materials, organic electrodes, secondary batteries, anti-corrosion coatings, antistatic materials (ESD), electromagnetic shielding coatings (EMI), electrochromism Coatings, light-emitting diodes, optics and nonlinear optical devices, etc., require polyaniline to be applied in the form of coatings more widely than the overall application. However, it is well known that due to the stro...
