Abstract:

Graphene oxide modified superabsorbent combines the advantages of graphene oxide and superabsorbent, and has a broad application prospect in the fields of water treatment adsorption, drug slow release and tissue engineering. At present, the preparation methods, properties and applications of graphene oxide modified superabsorbents have not been reviewed. Therefore, this paper was mainly divided into four parts to review the research progress of graphene oxide modified superabsorbent in recent years. In the first part, the structural properties of graphene oxide and its properties as a superabsorbent modifier were briefly introduced. In the second part, the main preparation processes of graphene oxide modified superabsorbent were summarized. The third part mainly presented the effect of graphene oxide on the microstructure and properties of superabsorbent. Finally, the applications of graphene oxide modified superabsorbent in wastewater treatment, reduction of “heat island effect”, flexible devices and medical materials were proposed, and the existing problems were analyzed, which provided the references for the follow-up research and application of graphene oxide modified superabsorbent.

Key words: graphene oxide, modification, superabsorbent, adsorption, polymerization

摘要：

氧化石墨烯改性吸水树脂综合了氧化石墨烯和吸水树脂的优势，在水处理吸附、药物缓释、组织工程等领域有广阔的应用前景。目前有关氧化石墨烯改性吸水树脂的制备方法、性能及应用缺少相关的综述。因此，本文主要分四部分来综述近几年氧化石墨烯改性吸水树脂的研究进展。第一部分简要介绍了氧化石墨烯的结构特性及作为吸水树脂改性剂的特点；第二部分主要综述了氧化石墨烯改性吸水树脂的主要聚合工艺；第三部分主要介绍了氧化石墨烯对吸水树脂微观结构和宏观性能的影响；最后，介绍了氧化石墨烯改性吸水树脂在废水处理、缓解“热岛效应”、柔性器件及医用材料等领域的应用，并分析了其存在的问题，为后续开展氧化石墨烯改性吸水树脂的相关研究及应用提供了参考。
