摘　　要：通过将具有良好弹性的TPU加入PS溶液中进行静电纺丝,成功制备出一系列不同比例的PS/TPU复合纳米纤维膜。润湿性测试结果表明:纤维膜具有疏水亲油性质。吸油性能表明:PS/TPU复合纳米纤维膜具有高吸油性能,且随着纳米纤维膜中TPU含量的增加,纳米纤维膜对机油、硅油、花生油的吸油量逐渐减小。同时,该复合纳米纤维膜具有良好的循环利用性能,因此该复合纳米纤维膜在处理油污污染方面具有很好的应用前景。PS/TPU solution was prepared by adding polymer（TPU）into PS solution to form the electrospinning precursor.And then,TPS/TPU composite nanofibrous membranes were successfully fabricated by electrospinning technique.The wettability revealed that the membranes had the ability of hydrophobicity and oleophilicity.The oil adsorption results showed that the membranes possessed high adsorption capacity for oil.In addition,the adsorption capacity for motor oil,silicon oil and peanut oil decreased with increasing the quality of TPU.Moreover,the freestanding membranes showed excellent cyclic utilization performance.Therefore,such novel composite nanofibrous membranes can be potentially widely used in the cleanup of oil from water.
