摘要
膜污染制约着膜分离技术的可持续发展。新型抗污染膜材料的研发是膜技术进一步发展的关键突破口,通过改性提升现有膜材料的抗污染性能一直是膜技术领域的研究热点。石墨烯因具有诸多独特的理化特征,近年来在膜改性领域备受关注。文章综述了不同石墨烯类材料的特点以及常用的膜改性方法,并详细阐述了石墨烯类材料在反渗透、正渗透、纳滤、超/微滤、渗透汽化以及导电膜领域内的膜改性研究及应用进展,并对今后的研究发展进行了展望,旨在推进新型膜材料的实际应用进展。
The sustainable development of membrane separation technology is tenaciously hampered due to membrane fouling. A further augmentation of membrane technology highly depends on an innovation of novel antifouling membrane materials. Membrane modification,as an alternative approach to enhancing the antifouling properties of existing membrane materials,has attracted great attentions in recent decades. Graphene,owing to its unique physicochemical characteristics,has been widely used for membrane modification in the past years. The paper summarized the features of graphene and its derivatives, and typical strategies for membrane modification. Research progress of membrane modification using graphene-based materials in the areas of reverse osmosis, forward osmosis, nanofiltration, ultra-/microfiltration,pervaporation, and conductive membranes was elaborated. In the end, prospective tendencies for further research development were proposed,aiming to propel the application of novel membrane materials.
