【 摘 要 】

In the present paper, PES-C nanofibrous membranes were prepared via solution-blowing technology and the crosslinked-PVP (PVPP) solution was sprayed on the PES-C substrate via homemade solution-blowing apparatus. Then the PVPP was melted and pressed into an integrated barrier film on the supporting layer by hot-pressing treatment. The depositing time of PVPP spray was optimized to achieve an integrated, nonporous PVPP barrier layer. The composite membranes were characterized by scanning electron microscopy (SEM), wide-angle X-ray diffraction (WAXD) and the water contact angles (WCA), etc. Furthermore, the filtration separation experiments of bovine serum albumin (BSA) was executed and antifouling property was measured by comparing the flux recovery ratio (FRR%). The results showed the composite membranes with PVPP-modified possessed an excellent and stability antifouling performances and could be applied in ultrafiltration field.
