摘　　要：选择常用的聚结除油材料聚四氟乙烯(PTFE),将其表面负载聚苯胺(PANI),成功构建超疏水纤维,并将其与亲水棉(Cot)纤维编织成超疏水/亲水异质材料(PANI/PTFE-Cot)用于处理含油废水。结果表明,具有微/纳结构的PANI成功负载在PTFE上,苯胺的投加量和反应温度影响PANI/PTFE的疏水性能。当反应温度为25℃,苯胺投加量为0.2 mol/L时,其水接触角达到最大,为154°。当PANI/PTFE和Cot纤维数量比为2∶1时,除油效果最佳。与传统的聚结材料PTFE相比,超疏水-亲水PANI/PTFE-Cot异质聚结材料的品质因子提高了46.7%。In this study,polytetrafluoroethylene(PTFE),a commonly used coalescence oil removal material,was selected and loaded with polyaniline(PANI) on its surface to successfully construct a superhydrophobic fiber material.It was then woven with hydrophilic cotton(Cot) fibers to form a superhydrophobic/hydrophilic heterogeneous material(PANI/PTFECot) for the treatment of oily wastewater.The results indicated that PANI with micro-nano structure was successfully loaded on PTFE fibre,and the dosage of aniline and reaction temperature affected the hydrophobicity of PANI/PTFE.When the reaction temperature was 25 ℃ and the dosage of aniline was 0.2 mol/L,the water contact angle reached its maximum of 154°.Compared with that of PTFE,the quality factor of 2∶1 PANI/PTFE-Cot increased 46.7%.
