摘要
随着现代工业的发展,重金属离子、染料和油类污染物等引起的环境问题日益严峻,严重影响生态环境和人类健康.聚合物微球因具有高比表面积,吸附性能强,易于功能化等优点而被广泛应用于水处理领域,开发简便、高效、绿色的聚合新方法,制备表面具有高密度功能性基团的聚合物微球具有重要科学价值和实际意义.近年来,本课题组提出了“自稳定沉淀聚合”(2SP聚合)的微球绿色制备技术,简单、高效地设计制备出核壳、空心、多孔等多种拓扑结构的聚合物微球,因含有大量的活性基团和发达的多级孔道结构,在环境治理领域取得了广泛的应用.本专论主要介绍了通过2SP聚合对聚合物微球组成和拓扑结构进行设计,并利用表面活性基团进行化学改性,进一步讨论其在染料、抗生素、重金属离子吸附分离,负载型催化剂制备,膜分离(含油污水)等水处理领域的应用前景及研究进展.
With the development of modern industry,water pollutions caused by heavy metal ions,organic dyes and oil pollutants have become more and more severe,which constituted a serious threaten to ecological environment and human health.Polymer microspheres are widely used in the field of water treatment due to their high specific surface area,good adsorption properties and easy functionalization.It is of great scientific value and practical significance to develop a facile,efficient and environmentally friendly polymerization method for the preparation of polymer microspheres with high density functional groups.In recent years,our research group has developed a novel green heterogeneous polymerization technique named“Self-Stabilized Precipitation Polymerization”(2SP polymerization),which allows for the simple and efficient design and preparation of polymer microspheres with various topological structures,including core-shell,hollow,and porous structures.Benefiting from both high density of functional groups and abundant multilevel porous structure,these microspheres have been widely applied in water treatment.In this feature article,the design and preparation of microspheres with tunable composition and topological structure by 2SP process were discussed in detail.Furthermore,the reactive groups on the surface of the polymer microspheres can be facilely chemically modified,and these modified microspheres can be applied in water treatment fields,such as adsorption/separation of dyes,antibiotics and heavy metal ions,preparation of supported catalysts and membrane separation(for oily wastewater).
