摘　　要：利用磁控溅射法在聚丙烯(PP)纤维膜上溅射SiO2纳米粒子,制备超疏水超亲油纤维膜,用于油水分离领域中。在PP纤维膜上溅射SiO2纳米粒子增加表面粗糙度,降低表面能达到超疏水的效果。通过调节溅射功率,改变疏水效果,当溅射功率为100W时,纤维膜的疏水性能最好,对水的接触角高达162.8±2.1°,对油的接触角为0°。更重要的是,PP-SiO2纤维膜在油水分离过程中仅仅依靠重力驱动,能够使油和水快速分离并且重复使用10次之后依然保持超疏水性,分离效率保持在90%左右,这将在工业油污和海洋溢油处理中,提供了新的材料。Superhydrophobic and superoleophilic melt-electrospun nanofibrous membranes exhibiting excellent oil/ water separation performance were green fabricated by a facile route magnetron sputtering silica nanoparticles onto the PP membranes. By introducing the rough structures and low surface energy, the nanofibrous membranes could he endowed with a superhydrophobicity with water contact angle of 162.8± 2.1°, a superoleophilicity with oil contact angle of 0°. More im- portantly,the PP-SiO2 membranes exhibited the excellent separation capability and stability for oil/water separation by a solely gravity-driven process. This separation membranes prepared after repeated use 10 times remained superhydrophobic and separation efficiency remained above 90 % ,which would make them a promising candidate for industrial oiI-contamina- ted water treatments and marine spilt oil cleanup.
