In order to solve the problem caused by oil spills and organic solvent contamination, novel magnetically inorganic/organic superhydrophobic fabrics are fabricated via a facile method. Cotton fabrics are immersed in a mixture of functionalized Co0.2Mg0.8Fe2O4 (FCMFO) nanoparticles, vinyl-terminated polydimethylsiloxane (VPDMS), trimethylolpropane triacrylate, and 2-hydroxy-2-methylpropiophenone before UV irradiation for 100 s to obtain the multifunctional superhydrophobic fabrics with magnetic property. The coated fabrics show excellent superhydrophobicity, and the water contact angle is 157.1° when the mass ratio of FCMFO nanoparticles to VPDMS is 0.3. These superhydrophobic fabrics have high oil/water separation efficiency (98.7% for dichloromethane/water) and high oil flux (71,506 L·m–2·h–1 for dichloromethane/water). Even after 20 separation cycles, oil/water separation efficiency and oil flux maintain 96.4% and 64,012 L·m–2·h–1, respectively. Furthermore, the magnetic property of these superhydrophobic fabrics could be used in the separation of oil from water. Moreover, the superhydrophobic fabrics possess exceptional self-cleaning performance, mechanical durability, chemical stability, and flame retardancy. These multifunctional superhydrophobic fabrics are potential for wide applications.

磁性无机/有机超疏水织物的制备及其应用。
为了解决由漏油和有机溶剂污染引起的问题，通过简便的方法制造了新颖的磁性无机/有机超疏水织物。将棉织物浸入功能化的Co 0.2 Mg 0.8 Fe 2 O 4混合物中（FCMFO）纳米粒子，乙烯基封端的聚二甲基硅氧烷（VPDMS），三羟甲基丙烷三丙烯酸酯和2-羟基-2-甲基苯乙酮在紫外线照射前100 s，以获得具有磁性的多功能超疏水性织物。当FCMFO纳米颗粒与VPDMS的质量比为0.3时，该涂层织物显示出优异的超疏水性，并且水接触角为157.1°。这些超疏水性织物具有很高的油/水分离效率（二氯甲烷/水为98.7％）和高油通量（二氯甲烷/水为71,506 L·m –2 ·h –1）。即使经过20个分离循环，油/水分离效率和油通量仍保持96.4％和64,012 L·m –2 ·h –1， 分别。此外，这些超疏水织物的磁性可用于油与水的分离。而且，超疏水织物具有出色的自洁性能，机械耐久性，化学稳定性和阻燃性。这些多功能超疏水性织物具有广泛的应用潜力。
