| 摘 要： | 以聚砜(PSF)为膜材料,水为凝胶剂,采用浸没沉淀相转化法制备PSF超滤膜,在制膜过程中添加亲水性聚合物聚乙烯基吡咯烷酮(PVP)和络合剂FeCl_2,改变PSF膜的亲水性,并对其性能进行表征。通过对PSF膜的共混改性制备低分子截留超滤膜。分析了铸膜液温度、凝胶浴温度及支撑层对PSF膜性能的影响,通过控制实验条件,制备出截留分子量为2000~10000的超滤膜。 |

| Abstract: | A new type of ultrafitration membrane with small molecular weight cut-off (MWCO), with PSF, with DMAC, with polyvinyl pyrrolidone (PVP) and FeCl2 as its raw materials, is prepared by means of the phase inversion method. The morphology of the membrane is controlled by adjusting the temperature of the casting solution, the temperatures of the coagulation bath and the support layer of membrane. The prepared ultrafitration membrane intercepts the matter of molecular weight: 2000-10000 with the interception rate of PEG of over 90% under the controlled process condition. |
