Embodiment 1
[0016] 1) Put the montmorillonite into a round-bottomed flask with a branch, vacuumize and fill with argon twice, add comonomers equivalent to 0.05 times the weight of the montmorillonite, and the comonomers are aniline and 2,5-bis The molar ratio of methoxyaniline, aniline and 2,5-dimethoxyaniline is 1:3. After magnetic stirring, the round bottom flask is covered with tinfoil paper, and placed in the dark at room temperature for 24 hours to obtain a blended suspension;
[0017] 2) Grind the blended suspension with a mortar for 5 minutes, add ammonium persulfate, the molar ratio of ammonium persulfate and comonomer is 1:1, during the grinding process, cover the mortar with a funnel, and let argon flow through one end of the funnel , continue to grind for 0.5 hours until it becomes completely purple-black;
[0018] 3) After the reaction, wash with water and absolute ethanol respectively, filter, and vacuum-dry to constant weight to obtain a montmorillonite intercalation nanocom...
Embodiment 2
[0020] 1) Put the kaolinite into a round-bottomed flask with a branch, evacuate and fill it with argon three times, add comonomers equivalent to 3.5 times the weight of kaolinite, and the comonomers are aniline and 2-methylaniline , the molar ratio of aniline and 2-methylaniline is 3:1, after magnetic stirring, the round-bottomed flask is covered with tinfoil, and placed in the dark at room temperature for 48 hours to obtain a blended suspension;
[0021] 2) Grind the blended suspension with a mortar for 10 minutes, add potassium dichromate, and the molar ratio of potassium dichromate and comonomer is 1:10. During the grinding process, cover the mortar with a funnel, and open one end of the funnel Argon, continue to grind for 1.2 hours until completely purple-black;
[0022] 3) After the reaction, wash with water and absolute ethanol respectively, filter, and vacuum-dry to constant weight to obtain a kaolinite intercalation nanocomposite.
Embodiment 3
[0024] 1) Put the montmorillonite into a round-bottomed flask with a branch, evacuate and fill it with argon for 3 times, add comonomers equivalent to 1.5 times the weight of the montmorillonite, and the comonomers are aniline and 2-aminobenzoic acid , the molar ratio of aniline to 2-aminobenzoic acid is 1:1, after magnetic stirring, the round-bottomed flask is covered with tinfoil, and placed in the dark at room temperature for 24 hours to obtain a blended suspension;
[0025] 2) Grind the blended suspension with a mortar for 5 minutes, add potassium iodate, and the molar ratio of potassium iodate and comonomer is 1:2. During the grinding process, cover the mortar with a funnel, and argon is passed through one end of the funnel , continue to grind, the grinding time is 0.7 hours, until it becomes completely purple-black;
[0026] 3) After the reaction, wash with water and ethanol respectively, filter, and vacuum-dry to constant weight, and intercalate the nanocomposite materi...
