摘要：
High flux ultrafiltration (UF) membranes based on electrospun polyacrylonitrile (PAN) nanofibrous substrates and cellulose acetate (CA) hydrophilic coatings have been demonstrated. Scanning electron microscopy (SEM) was used to examine the surface and cross sectional morphologies of these composite membranes. The results showed that the surface of the membranes was flat and smooth, and the CA coating was penetrated into the electrospun nanofibrous substrate. Concentration effect of CA in the coating solution on filtration properties of the composite membranes was investigated. The experimental results showed that the composite membrane of 10wt% CA coating solution possessed high water flux (310L.m(-2).h(-1)) with good organic rejection rate (95.5%) for oil/water emulsion separation, and the composite membranes performed higher rejection rate and lower flux with the CA concentration increasing.
