中文摘要：

为了探讨共混碳纳米管改善超滤膜抗污染性能的可行性，首次采用浸没沉淀相转化法（L-S法）制备了单壁碳纳米管（SWCNTs）及聚氯乙烯（PVC）共混膜并对其基本性质进行了表征．发现SWCNTs在聚氯乙烯铸膜液中表现出良好的分散性能，SWCNTs／PVC共混膜表面分布均匀微孔，断面形成不对称膜孔道．经SWCNTs共混后，PVC膜表面亲水性得到改善，当SWCNTs含量分别为0．1％，0．5％，1％，1．5％时，SWCNTs／PVC表面接触角分别降低了2．2％、6．5％，7．6％、8．2％，SWCNTs／PVC共混膜纯水通量较PVC膜明显提高．

英文摘要：

In order to explore the feasibility of using carbon nanotube to improve the anti-pollution performance ofuhrafiltering, single wall carbon nanotubes （SWNTs） and polyvinylchloride （PVC） blended membranes were first proposed and prepared by a phase inversion process in the presented research. The basic performance was charac-terized with a series of analysis methods. SWCNTs showed very good dispersing properties. Very tiny and mean pores were formed on the SWCNTs/PVC blended membrane surfaces. The pores were of asymmetric structure froma cross section view. After blending with the SWCNTs, the hydrophilicity of the PVC membrane was improved. When the contents of the SWCNTs were 0.1%, 0.5%, 1%, and 1.5%, respectively, the surface contact anglesof the SWCNTs/PVC membrane were reduced by 2.2% , 6.5%, 7.6%, and 8.2% accordingly. The pure water flux of the SWCNTs/PVC blended membrane was improved compared with a purely PVC membrane.
