【摘要】 基于二维材料MXene（Ti₃C₂T_x）的化学组成和纳米片状结构,在不锈钢网上制备了具有MXene微纳结构表面的新型亲水和水下超疏油分离膜.对于不同类型的油-水混合物,该膜材料可实现重力驱动的高效油水分离,收集的水中残油量小于4 mg/L,具有高分离效率（>99. 99%）,水通量高达57. 52 L·m^-2·s^-1.此外,经高温处理和多种有机溶剂浸泡后MXene膜仍具有高效的油水分离性能,并表现出优异的稳定性和循环性.更多还原

【Abstract】 Owing to the hydrophilicity and flake-like structure of the two-dimensional（ 2D） MXene（ Ti₃C₂T_x）,the 2D MXene nanosheets were coated onto the stainless steel mesh to fabricate a novel hydrophilic and underwater superoleophobic mesh membrane with a corrugated micro-and nanostructure surface. For a series of oil-water mixtures,the MXene-caoted mesh membrane can achieve gravity-driven highefficiency oil-water separation with excellent separation efficiency of over 99.99%,residual oil content of less than 4 mg/L in collected water,and water flux up to 57. 52 L·m^-2·s^-1. In addition,MXene-coated mesh membranes display outstanding stability and cycleability.更多还原
