摘要:: 氧化石墨烯（GO）是最薄的二维纳米材料，具有丰富的含氧官能团、大的比表面积、良好的机械及热稳定性，是近年来比较热门的新型材料。为改善单一GO膜在水溶液中因静电排斥、水合作用和团聚效应导致的分离性能下降的问题，基于聚合物膜较高的化学和机械稳定性、抗氧化性和生物相容性，将聚合物与GO膜结合制备得到GO/聚合物复合膜，可以有效增强单一GO膜的渗透率和污染物拦截率，提高膜稳定性，在水处理方面具有广阔的应用前景。综述了GO/聚合物复合膜的制备方法，分析了GO/聚合物复合膜去除污染物的机理，介绍了GO/聚合物复合膜在水处理领域的应用。最后，对GO/聚合物复合膜未来的研究方向做了进一步展望。

Abstract:: Graphene oxide (GO) is the thinnest two-dimensional nanomaterial with abundant oxygen-containing functional groups, large specific surface area, and excellent mechanical and thermal stability, which is a relatively hot new material in recent years. In order to address the issue of reduced separation performance caused by electrostatic repulsion, hydration and agglomeration effects of single GO membranes in aqueous solutions, GO and polymer membrane can be combined to prepare composite membrane based on the high chemical and mechanical stability, oxidation resistance and biocompatibility of polymer membranes. The GO/polymer composite membranes can effectively enhance the permeability, contaminant retention rate, and stability of a single GO membrane, which have a broad application prospect in water treatment. In this paper, the preparation methods of GO/polymer composite membrane were reviewed, the removal mechanism of pollutants was analyzed and the application of composite membrane in the fields of water treatment was summarized. Finally, the future research direction of composite membrane was further prospected.
