Problems solved by technology

However, the functionalized conductive polymer prepared by the "one-step method" generally only has one monomer, aniline, pyrrole, thiophene, etc., and magnetic particles, which limits the further improvement of the electrical and magnetic properties of the electromagnetically functionalized conductive polymer.

Embodiment 1

[0033] This example relates to a one-step method for synthesizing magnetic nanoparticles coated with aniline-aniline derivative copolymer. Specifically, aniline and m-aminobenzenesulfonic acid were added into a certain amount of 10 mL of 1M ammonia water at a molar ratio of 1:1, and ultrasonically dispersed to form a white emulsion. Then the white emulsion was stirred in a water bath at 37°C at 300 rpm, and after constant temperature, 1.8 mmol of ferrous chloride aqueous solution was added thereto, and then 45 mmol of ferric chloride solution was added dropwise. The system was allowed to react with stirring for 12 h to obtain a black solid. The resulting black solid was filtered, washed with distilled water until neutral, washed with ethanol until colorless, and finally washed three times with ether and dried in vacuum to obtain Fe coated with aniline-m-aminobenzenesulfonic acid copolymer. 3 o 4 magnetic nanoparticles.

Embodiment 2

[0035] This example relates to a one-step method for synthesizing magnetic nanoparticles coated with aniline-aniline derivative copolymer. Specifically, aniline and m-aminobenzoic acid were added to a certain amount of 10 mL of 1M ammonia water at a molar ratio of 1:1, and ultrasonically dispersed to form a white emulsion. Then the white emulsion was stirred in a water bath at 37°C at 300 rpm, and after constant temperature, 1.8 mmol of ferrous chloride aqueous solution was added thereto, and then 45 mmol of ferric chloride solution was added dropwise. The system was allowed to react with stirring for 12 h to obtain a black solid. The resulting black solid was filtered, washed with distilled water until neutral, then washed with ethanol until colorless, and finally washed three times with ether and dried in vacuum to obtain Fe coated with aniline-m-aminobenzoic acid copolymer. 3 o 4 magnetic nanoparticles.

Embodiment 3

[0037] This example relates to a one-step method for synthesizing magnetic nanoparticles coated with aniline-aniline derivative copolymer. Specifically, aniline and o-methylaniline were added into a certain amount of 10 mL of 1M ammonia water at a molar ratio of 1:1, and ultrasonically dispersed to form a white emulsion. Then the white emulsion was stirred in a water bath at 37°C at 300 rpm, and after constant temperature, 1.8 mmol of ferrous chloride aqueous solution was added thereto, and then 45 mmol of ferric chloride solution was added dropwise. The system was allowed to react with stirring for 12 h to obtain a black solid. The resulting black solid was filtered, washed with distilled water until neutral, then washed with ethanol until colorless, and finally washed three times with ether and dried in vacuum to obtain Fe coated with aniline-o-methylaniline copolymer. 3 o 4 magnetic nanoparticles.
