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 asy...
