侧链液晶聚醚螯合树脂研究进展

Research Progress in Side Chain Liquid Crystalline Polyether Chelating Resin

相对于传统聚醚螯合树脂,侧链液晶聚醚型螯合树脂由于刚性介晶基元的引入,赋于了聚醚分子更好的使用性能,具有热稳定性好、吸附容量大、离子选择性高、易于设计与合成等优势,成为近年来树脂领域研究的热点之一。本文介绍了近年来国内外侧链液晶聚醚螯合树脂的合成、性能与应用现状。最后依据对侧链液晶聚醚螯合树脂机械性能、吸附选择性、再生性能以及环保性能的使用要求,对其分子设计与合成方法及新应用领域进行了展望。

Side chain liquid crystalline polyether chelating resins have greater application performance than traditional polyether chelating resin owing to introduction of rigid mesogenic. They have become one of the hot spots in the field of resin in recent years with the advantages of good heat stability,adsorption capacity,ion selectivity,and easy design and syntheses. This paper introduces the syntheses,properties and application of side chain liquid crystalline polyether chelate resins. Finally,based on the requirements for the use of the mechanical properties,adsorption selectivity,regeneration performance,and environmental performance of the side chain liquid crystalline polyether chelate resins,the molecular design,synthetic methods and new application fields are prospected.
