Electrofiltration, an effective approach for membrane fouling mitigation, is significantly limited by membrane properties. A facile electrochemical method was proposed to fabricate the graphene oxide/sulfuric acid-doped polyaniline (GO/S-PANI) membrane. For which, charging the graphite in H₂SO₄ (98 wt%) to obtain graphite intercalation compound (GIC), then in a mixed electrolyte (H₂SO₄, CuSO₄, (NH₄)₂SO₄), GO was exfoliated and assembled concurrently on the PANI membrane, which was doped by H₂SO₄ simultaneously. The introduction of Cu²⁺ made the GO layers on the membrane stable. Also, the GO/S-PANI membrane showed higher conductivity (55.6 S m⁻¹) than the PANI membrane (0.019 S m⁻¹). Moreover, GO/S-PANI membrane possessed a more applicable pore structure and improved hydrophilicity. As a result, membrane rejection increased, and the resistance to the negatively charged pollutants was enhanced. For 1 V electrofiltration of yeast suspension, water permeation was sustainably raised by using GO/S-PANI membrane than PANI membrane. The GO/S-PANI membrane was more stable with 1 V than without electric fields. The antibacterial rate can reach 92.1% for the GO/S-PANI membrane against Escherichia coli. Overall, our strategy provides a facile preparation method for the GO/S-PANI conductive membrane with application potential in electrofiltration and antibacterial fields.

电过滤是一种有效的减少膜污染的方法，但受到膜特性的显着限制。提出了一种简便的电化学方法来制造氧化石墨烯/硫酸掺杂的聚苯胺（GO/S-PANI）膜。为此，将石墨装入 H ₂ SO ₄ (98 wt%) 中以获得石墨插层化合物 (GIC)，然后在混合电解质 (H ₂ SO ₄、CuSO ₄、(NH ₄ ) ₂ SO ₄ ) 中，GO 为在同时掺杂 H ₂ SO ₄的 PANI 膜上同时剥离和组装。Cu ²⁺的引入使膜上的 GO 层稳定。另外，GO / S-PANI膜显示出更高的电导率（55.6 S M ^-1比PANI膜）（0.019 S M ^-1）。此外，GO/S-PANI膜具有更适用的孔结构和更好的亲水性。结果，膜截留率增加，对带负电荷的污染物的抵抗力增强。对于酵母悬浮液的 1 V 电过滤，使用 GO/S-PANI 膜比使用 PANI 膜可持续提高水渗透率。GO/S-PANI 膜在 1 V 电压下比没有电场时更稳定。GO/S-PANI膜对大肠杆菌的抑菌率可达92.1%。总的来说，我们的策略为在电过滤和抗菌领域具有应用潜力的 GO/S-PANI 导电膜提供了一种简便的制备方法。
