摘　　要：采用浸没沉淀相转化法制备复合CNTs的PSA超滤膜,以水通量和截留率为指标,优化复合CNTs的PSA超滤膜的制备条件。实验结果表明,在搅拌温度70℃、CNTs添加量0.6%、PSA含量11%、PVP含量1%、搅拌时间8 h条件下,所制备的复合CNTs的PSA超滤膜水通量可达589.76 L/(m^(2)·h),截留率88.2%,平均孔径54.6 nm,孔隙率74.8%,通量恢复率达78.1%,拉伸强度可达3.97 N/mm^(2);与未添加CNTs的PSA超滤膜相比,复合CNTs的PSA超滤膜水通量提高262.11 L/(m^(2)·h),截留率提高4.3%,孔隙率增加42.6%,通量恢复率提高11.9%。PSA composited CNTs ultrafiltration membrane was prepared by immersion-precipitation phase conversion method.The preparation conditions of PSA composited CNTs ultrafiltration membrane were optimized with water flux and retention rate as indexes.The experimental results showed that under the conditions of stirring temperature 70℃,CNTs addition amount 0.6%,PSA content 11%,PVP content 1% and stirring time 8 h,the water flux of PSA composited CNTs ultrafiltration membrane could reach 589.76 L/(m^(2)·h),the interception rate was 88.2%,the average pore diameter was 54.6 nm,the porosity was 74.8%,the flux recovery rate was 78.1%and tensile strength was 3.97 N/mm^(2);Compared with PSA ultrafiltration membrane without CNTs,the water flux of PSA composited CNTs ultrafiltration membrane increased by 262.11 L/(m^(2)·h),the interception rate increased by 4.3%,the porosity increased by 42.6%,and the flux recovery rate increased by 11.9%.
