Example Embodiment
[0031] Example 1
[0032] Disperse 0.6 mL of N-vinylimidazole, 0.6 mL of ethylene glycol dimethacrylate, and 0.018 g of azobisisobutyronitrile into 80 mL of acetonitrile, heat to reflux at 82°C, and centrifuge the resulting product with acetonitrile 2 Then, it was centrifuged and washed once with absolute ethanol to obtain imidazole nanospheres.
[0033] Disperse 0.6 g of the prepared imidazole nanospheres and quaternization reagent (using 2.40 mL ethyl chloroformate, 1.32 mL chloro-n-butane, and 1.48 mL benzyl chloride) into absolute ethanol (120 mL). Heat to reflux for 20h at 70°C under nitrogen protection. The reacted solution was centrifuged and washed with absolute ethanol for 3 times, and it was dried in a vacuum drying oven for 24 hours to obtain E-QPVI, C 4 -QPVI, B-QPVI quaternized nanospheres.
[0034] In the preparation process of the organic nanocomposite membrane, the quaternized imidazole nanospheres (0.048g) were added to 10mL of deionized water and stirred ultrasoni...

[0038] Example 2
[0039] Disperse 0.6 mL of N-vinylimidazole, 0.6 mL of ethylene glycol dimethacrylate, and 0.018 g of azobisisobutyronitrile into 80 mL of acetonitrile, heat to reflux at 82°C, and wash the resulting product with acetonitrile centrifugal 2 Then, it was centrifuged and washed once with absolute ethanol to obtain imidazole nanospheres.
[0040] Disperse 0.6 g of the prepared imidazole nanospheres and 2.4 mL of ethyl chloroformate in 120 mL of absolute ethanol, and heat to reflux for 20 hours at 70° C. under nitrogen protection. The reacted solution was centrifuged and washed with absolute ethanol for 3 times, and dried in a vacuum drying oven for 24 hours to obtain E-QPVI quaternized imidazole nanospheres.
[0041] During the preparation process of the organic nanocomposite membrane, 0.024 g of E-QPVI was added to 10 mL of deionized water, and ultrasonically stirred (the ultrasonic time was greater than 4h). 1.2 g of chitosan was added to 45 mL of deionized water, 1...
