| 英文摘要 | Heavy crude oil/water separation is becoming a worldwide issue and a tougher challenging as compared to light crude oil due to its high viscosity. Herein, we report a facile approach for high-efficient heavy oil/water separation by combing superwetting membrane filtration with elevated temperature during separation process. Micro/nano hierarchical PAA-g-PVDF layer coated nickel foam membranes are successfully fabricated through a salt-induced phase inversion process. The PAA-g-PVDF coating layer endows the foam membrane a superhydrophilic and underwater superoleophobic property, and a low heavy-oil-adhesion force. At an elevated temperature (up to 85 degrees C) where the viscosity of heavy oil is dramatically decreased with the increase of temperature, the foam membranes are applicable for temperature-controlled separation of heavy oil/water mixture with various heavy oil/water volume ratio with high separation efficiency (the contents of heavy oil in the filtrate after one-time separation <20 ppm) and high flux up to similar to 10(4) L m(-2) h(-1), solely driven by gravity. Most importantly, the foam membrane exhibits an excellent anti-heavy-oil-fouling property and is easily recycled for long-term use. The high separation performance with elevated temperature, combined with easy scale up, makes the foam membranes an attractive option for treating heavy oil containing wastewater.
