摘要

采用水浴法和真空抽滤等方法,在棉布表面成功制备了具有微纳米级粗糙结构的Fe₃O₄/石墨烯/硬脂酸复合膜,与原始棉布相比,复合膜表现出从超亲水到超疏水的显著变化,水接触角达到156.1°。此外,复合膜在不同pH环境下表现出稳定的超疏水性,对多种油水混合物的分离效率均高于98.4%。并且分离效率和通量在10个循环内没有表现出显著的波动,仍然保持在98%以上。

Abstract

Fe₃O₄/graphene/SA composite membrane with a micro- and nanoscale rough structure was successfully prepared on the surface of cotton fabric by using water bath and vacuum filtration methods.Compared with the original cotton fabric,the composite membrane exhibited a significant change from superhydrophilic to superhydrophobic,and the water contact angle reached 156.1°.Moreover,the composite membrane demonstrated stable superhydrophobicity under different pH environments,and the separation efficiency was higher than 98.4% for a variety of oil-water mixtures.The separation efficiency and flux did not show significant fluctuations within 10 cycles and remained above 98%.
