Preparation process description:
1. Take 50 ml of 0.5 mol/L H₂SO₄;
2. Add 1.2 mmol of aniline monomer to the solution and sonicate at 1200W for 20 minutes to dissolve the aniline in sulfuric acid.
3. Take 100 ml of 1 mol/L H₂SO₄ solution;
4. Add 1 mmol ammonium persulfate and perform ultrasonication at 1200W for 20 minutes;
5. Slowly add the mixture obtained from step 4 to the mixture obtained from step 2; and under low temperature (＜10°C), magnetic stirring (rpm), react for 16 hours;
6. High-speed centrifugation (15000 rpm/15 min), collect the precipitate, and wash it three times successively with ethanol and distilled water.
7. Vacuum freeze-drying for 24 hours, then collect the product.
