| 英文摘要 | Treatment of oil/water mixture, especially oil/water emulsions, is of great significance in the protection of both the environment and living creatures. Herein, in this work, we reported a two-step strategy to enhance the hydrophilicity and underwater oleophobicity of PVDF microfiltration membranes using tannic acid (TA, a nature plant polyphenol) and AgNO3 solutions. After coating by Ag nanoparticles (AgNPs)/TA (0.4 mg/ml Ag+, 0.2 mg/ ml TA), the PVDF membrane exhibited high hydrophilicity for a short immersion time (10.35 s) of a water droplet (V=5 mu l, initial WCA=19), underwater superoleophobicity (UOCA=161) and antifouling property and thus, high-efficiency oil/ water emulsions (SDS/kerosene/water emulsion) separation could be realized. Compared with Fe/TA-PVDF (0.4 mg/ml Fe2+, 0.2 mg/ml TA, initial WCA=21 and UOCA=156) and Cu/TAPVDF (0.4 mg/ml Cu2+, 0.2 mg/ml TA, initial WCA=31 and UOCA=147), the AgNPs/TA-PVDF in our work possessed best hydrophilicity and underwater superoleophobicity. In addition, the AgNPs/TA-PVDF could maintain its hydrophilicity, underwater superoleophobicity and mechanical property after rinsing tests and scratch resistance tests. |
