摘要:

基于二维材料MXene(Ti3C2Tx)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.

Abstract:

Owing to the hydrophilicity and flake-like structure of the two-dimensional(2D) MXene(Ti3C2Tx), 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 high-efficiency 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.
