Abstract:

PVP/EVAL blend membranes was prepared by blending of PVP with poly(ethylene-co-vinylThe effect of PVP content on the separation performance of oil/water emulsion was investigated.The results indicate that PVP content had distinct effect on the morphology of PVP/EVAL membranes.of PVP in the casting solution) PVP were 1.88 and 1.34 times, respectively, that of pure EVAL membraneWhen the content of PVP increased to 4 wt%, oil/water emulsion flux of PVP/EVAL blend membrane were 1.81
