摘　　要：以PES为底膜,通过真空辅助自组装方法制得MoS_(2)/MXenes/PES复合膜,借助XRD、TEM、EDS、电位分析仪等对所制样品进行表征,并利用油/水乳化液分离测试研究了复合膜的油/水分离性能。结果表明,当MXenes纳米片添加量为0.2 mg时,所制MoS_(2)/MXenes/PES复合膜的水通量较高,对泵油、汽油、豆油和柴油均有较强的截留能力,并且循环使用性能稳定。MoS_(2)/MXenes/PES composite membranes were prepared by vacuum-assisted self-assembly(VASA) method with PES as the base membrane. The as-prepared samples were characterized by XRD, TEM, EDS and potential analyzer, and the oil-water separation performance of the composite membrane was studied via oil-water emulsion separation test. The results show that when the addition of MXenes nanosheets is 0.2 mg, the as-prepared MoS_(2)/MXenes/PES composite membrane has higher water flux, stronger interception capacity for pump oil, gasoline, soybean oil and diesel oil, and stable recycling performance.
