Examples
Embodiment 1
[0030] 5-sulfosalicylic acid and ε-caprolactam were selected as monomers, and the monomers were weighed at a mass ratio of 3:100 for polymerization. Weigh the product sulfonic polyamide 6 (1) 3g and 7g of formic acid with a mass concentration of 80%, all add to a 100mL single-necked bottle, stir at room temperature until dissolved, leave to defoam, and prepare a film casting solution with a mass fraction of 30%. Drop the cast film liquid onto a clean glass plate, scrape it into a thin layer with a film scraper, let it stand in the air for 2 minutes, and immerse it in a coagulation bath composed of 130mL ethanol, 370mL water and 100mL80% formic acid until the film solidifies detached from the glass plate. Wash with deionized water until the pH is neutral, record as membrane 1, and set aside.
Embodiment 2
[0032] 2-amino-5-sulfo-benzoic acid and ε-caprolactam were selected as monomers, and the monomers were weighed at a mass ratio of 2.5:100 for polymerization. Take by weighing product sulfonic acid group polyamide 6 (II) 3g and the formic acid 7g of mass concentration 80%, 0.01g surfactant A, all add 100mL one-necked bottle, stir at room temperature until dissolving, leave standstill defoaming, be mixed with mass fraction: 30% casting solution. Drop the cast film liquid onto a clean glass plate, scrape it into a thin layer with a film scraper, let it stand in the air for 1.5min, and immerse it in a coagulation bath composed of 130mL ethanol and 370mL water until the film solidifies from the glass Board comes off. Wash with deionized water until the pH is neutral, record as membrane 2, and set aside.
Embodiment 3
[0034] 5-sulfosalicylic acid and ε-caprolactam were selected as monomers, and the monomers were weighed at a mass ratio of 2:100 for polymerization. Take by weighing 3.1g of the product sulfonic acid polyamide 6 (I) and 6.89g of formic acid with a mass concentration of 80%, and 0.01g of surfactant B, all add to a 100mL single-necked bottle, stir at room temperature until dissolved, let stand for defoaming, and prepare a mass Casting solution with a fraction of 31%. Drop the cast film liquid onto a clean glass plate, scrape it into a thin layer with a film scraper, let it stand in the air for 2.5 minutes, and immerse it in a coagulation bath composed of 130mL ethanol, 370mL water and 100mL formic acid until the film solidifies detached from the glass plate. Wash with deionized water until the pH is neutral, record as membrane 3, and set aside.
