中文摘要：

氧化石墨烯（GO）作为一种新型二维材料,在能源、环境、石油化工、生物医药、光电材料、催化等领域有巨大的应用潜能。当氧化石墨烯膜用于分离时,有着与传统膜过程不同的分离机理。氧化石墨烯膜的层间距可以通过制备方法进行调节以实现离子、分子等物质的精确筛分。总结了由氧化石墨烯溶液制备氧化石墨烯膜的主要制备方法,如真空过滤法、旋涂法、浸涂法、静电自组装法等。

英文摘要：

As a kind of novel two-dimensional material, graphene oxide（GO） plays an important role in energy storage, environment protection, petrochemical industry, biological medicine, photoelectric materials,catalysis,etc. In separation, GO membrane is governed by the different separation mechanismfrom conventional membranes. Precise separation of ions or molecules can be realizedthroughcontrolling the interlayer distance of GO by changing the preparation methods. Several main methods to obtain GO membrane were summarized in this paper which include vacuum filtration, spin-coating, dip-coating, electrostatic self-assembly methods, etc.
