A superhydrophobic caffeic acid/Fe@cotton fabric (CfA/Fe@cotton fabric) was fabricated by a simple, high efficiency and environmentally friendly approach and the polymerization of caffeic acid was catalyzed by laccase. This superhydrophobic cotton fabric and caffeic acid/Fe hybrid particles (CfA/Fe) were characterized by scanning electron microscopy (SEM), atomic force microscope (AFM), X-ray diffraction (XRD) and so on. The results showed that the surface of cotton fiber was coated by CfA/Fe composite deposition film, and the ferrous ions can be reduced to zero valent iron particles with good crystal structure in the aging process of reaction. Compared with pristine cotton fabric, the superhydrophobic cotton fabric exhibited high water contact angle (CA) of about 158°. It could withstand various extreme conditions and 100 cycles of abrasion by friction tester without great changes of CA. In addition, CfA/Fe@cotton fabric had excellent self-cleaning and oil-water separation performance, and the oil separation efficiency was higher than 99%. Even after ten times of reuse, it still remained high efficiency separation ability. Moreover, this method has a certain degree of universality, the CfA/Fe can be deposited on many different substrates to form highly hydrophobic surfaces. This superhydrophobic cotton fabric has potential application value in oil-water separation, and this excellent preparation method also has broad application prospects.

通过简单，高效，环保的方法制备了超疏水咖啡酸/铁棉织物（CfA / Fe @棉织物），并用漆酶催化咖啡酸的聚合。通过扫描电子显微镜（SEM），原子力显微镜（AFM），X射线衍射（XRD）等对这种超疏水棉织物和咖啡酸/铁杂化颗粒（CfA / Fe）进行了表征。结果表明，棉纤维表面覆盖有CfA / Fe复合沉积膜，在反应时效过程中，亚铁离子可还原为具有良好晶体结构的零价铁颗粒。与原始棉织物相比，超疏水棉织物表现出约158°的高水接触角（CA）。它可以承受各种极端条件和摩擦测试仪的100次磨损循环，而CA不会发生很大变化。另外，CfA / Fe @棉织物具有良好的自洁性和油水分离性能，油分离效率高于99％。即使经过十次重用，它仍然保持了高效率的分离能力。而且，该方法具有一定程度的通用性，CfA / Fe可以沉积在许多不同的基底上以形成高度疏水的表面。该超疏水棉织物在油水分离中具有潜在的应用价值，这种优良的制备方法也具有广阔的应用前景。分油效率高于99％。即使经过十次重用，它仍然保持了高效率的分离能力。而且，该方法具有一定程度的通用性，CfA / Fe可以沉积在许多不同的基底上以形成高度疏水的表面。该超疏水棉织物在油水分离中具有潜在的应用价值，这种优良的制备方法也具有广阔的应用前景。分油效率高于99％。即使经过十次重用，它仍然保持了高效率的分离能力。而且，该方法具有一定程度的通用性，CfA / Fe可以沉积在许多不同的基底上以形成高度疏水的表面。该超疏水棉织物在油水分离中具有潜在的应用价值，这种优良的制备方法也具有广阔的应用前景。
