| 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.

| Abstract: | In order to explore the feasibility of using carbon nanotube to improve the anti-pollution performance of ultrafiltering,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 characterized 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 from a 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 angles of 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. |
