【摘要】 利用电化学聚合法将苯胺和不锈钢网制备了一种新型聚苯胺 (PANI) 复合导电膜。调整电化学 CV 循环为 560 圈，导电膜通量稳定在 6 900 L/(m~3· h · MPa)，可以较好地实现超滤膜的功能。利用SEM、EIS 和 CV 验证了该膜具有较好的电导率和稳定性。LC-OCD 对 BSA、SA 和 HA 3 种模拟污染物以及 SE 的 DOC 截留率分别达到 40.2%,85.6%,45.8%,26.5%，表明该导电膜比普通超滤膜具有较好的效果。抗污染试验表明 ：在通电反洗过程中 (2 V),PANI 导电膜可以实现广泛的通量恢复，无需消耗化学物质，尤其对大分子 BSA、SA 和小分子 HA 抗污染的效果更好。更多还原

【Abstract】 A novel polyaniline (PANI) composite conductive membrane is prepared by electrochemical polymerization of aniline and stainless steel mesh. Adjust the electrochemical CV cycle to 560, and the flux of the conductive membrane is 6 900L/(m~3·h·MPa) can better realize the function of ultrafiltration membrane. SEM, EIS and CV are used to verify that the membrane has better conductivity and stability. The DOC rejection rates of BSA, SA and HA simulated foulant and SE can reach 40.2%, 85.6%,45.8% and 26.5% by LC-OCD, respectively, showing the better effect of conductive membrane than ordinary ultrafiltration membrane.According to the anti-fouling test, PANI conductive membrane can achieve extensive flux recovery without chemicals under the poweron mode (2 V) during backwash, especially in dealing with the fouling of BSA, SA, HA.更多还原
