A modified layer of ZnO coating with the thickness of about 0.57 μm has been uniformly deposited on carbon cloth by microwave-assisted modification technology for reversing the wettability of carbon cloth, resulting in the fabrication of ZnO/CC Mem. The inherent properties of carbon fibers absorbing microwave radiation and converting it into volumetric heating contribute to the uniform deposition of ZnO modified coating on carbon cloth. After modification, the WCA of as-prepared ZnO/CC Mem is 0° while the corresponding UWOCA is up to 158.4 ± 1.1°, exhibiting the excellent superhydrophilicity/underwater superoleophobicity. In the process of gravity driven oil-water separation, a high filtrate flux about 18,625 ± 100 L/(m² h), is found in the separation of oil-water mixture, and the corresponding separation efficiency is 99.9%; While for the treatment of simulated kitchen oily wastewater, a bilayer ZnO/CC Mem is used. The corresponding filtrate flux and separation efficiency are 15,880 ± 100 L/(m² h) and 99.8%, respectively. In addition, the fouled ZnO/CC Mem could restore the virgin performance by a simple cleaning process.

通过微波辅助改性技术逆转碳布的润湿性，在碳布上均匀沉积了厚度约为0.57μm的ZnO涂层改性层，从而制备了ZnO / CC Mem。碳纤维吸收微波辐射并将其转换为体积加热的固有特性有助于ZnO改性涂层在碳布上的均匀沉积。改性后，所制备的ZnO / CC Mem的WCA为0°，而相应的UWOCA则高达158.4±1.1°，表现出优异的超亲水性/水下超疏油性。在重力驱动的油水分离过程中，高滤液通量约为18,625±100 L /（m ² h），发现在油水混合物的分离中，相应的分离效率为99.9％；在处理模拟厨房含油废水时，使用了双层ZnO / CC Mem。相应的滤液通量和分离效率分别为15880±100 L /（m ²  h）和99.8％。此外，结垢的ZnO / CC Mem可以通过简单的清洁过程恢复原始性能。
