Abstract：

The PDMS/PVDF nanofiber membrane was prepared by electrospinning method. Through the characterization of SEM, ATR-FTIR, EDS, AFM, water contact angle and the MARS tests, the PDMS/PVDF ratio was compared to the influence of membrane structure and performance. The experiments found that when PDMS:PVDF = 3:7, membrane MPDMS3 has the best micro-morphology with the thickness of 30 μm, water contact angle of 150°. And the total mass transfer coefficient Kov reaches 16.9 × 10-7 m/s at 25 ℃. The prepared membrane MPDMS3 was applied to membrane aromatic recovery system (MARS) and showed a good long-term stability. After 75 h, the phenol removal rate reached 99.7%.
