Pollutants in wastewater include oils, dyes, and bacteria, making wastewater cleanup difficult. Multifunctional wastewater treatment media consisting of poly(ionic liquid)‐grafted polypropylene (PP) nonwoven fabrics (PP@PIL) are prepared by a simple and scalable surface‐grafting process. The fabricated PP@PIL fabrics exhibit impressive switchable oil/water separation (η>99 %) and dye absorption performance (q=410 mg g⁻¹), as well as high antibacterial properties. The oil/water separation can be easily switched by anion exchanging of the PIL segments. Moreover, the multiple functions (oil/water separation, dye absorption, and antibacterial properties) occurred at the same time, and did not interfere with each other. The multifunctional fibrous filter can be easily regenerated by washing with an acid solution, and the absorption capacity is maintained after many recycling tests. These promising features make PIL‐grafted PP nonwoven fabric a potential one‐step treatment for multicomponent wastewater.

聚丙烯无纺布@聚（离子液体），用于可切换的油/水分离，染料吸收和抗菌应用

废水中的污染物包括油脂，染料和细菌，这使废水净化变得困难。通过简单且可扩展的表面接枝工艺，可以制备由聚（离子液体）接枝的聚丙烯（PP）无纺布（PP @ PIL）组成的多功能废水处理介质。制成的PP @ PIL织物具有令人印象深刻的可切换的油/水分离度（η > 99％）和染料吸收性能（q = 410 mg g ^-1），以及极高的抗菌性能。通过PIL段的阴离子交换可轻松切换油/水分离。而且，多种功能（油/水分离，染料吸收和抗菌性能）同时发生，并且不会互相干扰。多功能纤维过滤器可以通过用酸溶液洗涤而容易地再生，并且在多次循环测试之后保持了吸收能力。这些有前途的功能使PIL接枝的PP无纺布成为多组分废水的潜在一步处理方法。
