| Abstract:PAN micro-nanofiber membranes with different structures were prepared on the surface of substrate by changing the electrospinning time （1~4 h）. The membranes and substrate were combined and prepared composite filter paper， and the oil-water coalescence and separation performance of composite filter paper were explored under the conditions of low diesel interfacial tension （17 mN/m）， small particle size water droplets （Dx（50）=10±1.5 μm） and low moisture content （0.3%）. The results showed that as the electrospinning time increased， the oil-water coalescence and separation efficiency of the composite filter paper increased from 4.85% to 96.88%， and the pressure drop increased from 3.71 kPa to 8.10 kPa. When the spinning time was 1 h， the prepared filter paper composited with a nylon mesh showed relatively good oil-water coalescence and separation performance. |
