【摘要】 氧化石皇烯(GO)具有片层薄、亲水性好、水分子在其片层间运动速度快等特点,通过调节GO膜片层间隙尺寸可实现对溶质的截留,因而在水处理方面表现出优异的分离性能。本文综述了氧化石墨烯基膜的制备方法,包括真空抽滤法、喷涂法、旋涂法和浸涂法和层层自主装法等。介绍了氧化石墨烯基膜在反渗透、纳滤、渗透汽化等方面的研究进展,并对未来在水处理领域的应用进行了展望。更多还原

【Abstract】 The graphene oxide(GO) is a one-atom thick nanosheet with good hydrophilic properties and the water molecules move fast between GO layers.Adjusting the distance between GO membranes can achieve a good retention of the solute,with excellent separation performance in the water treatment.This paper reviews the preparation methods of GO-basedmembranes,including the vacuum filtration,the spray coating,the spin coating,the dip coating and the layer by layer self-assembly method.In addition,the research progress of GO-based membranes in reverse osmosis,nanofiltration and pervaporation is discussed in detail.The future applications of GO-based membranes in water treatment are discussed as well.更多还原
