离子印迹聚合物功能单体的研究进展

摘要

This paper is aimed to describe the research progress in several functional monomers in terms of their performance,advantages,and applications. The elaborated functional monomer contains the categories of organic acids (methacrylic acid,acrylic acid and vinyl benzoic acid),aromatic heterocyclic (pyridine , imidazole , amides and quinolines) , the Schiff base and Salen ligand. Furthermore,the adsorption characteristics and application performances of ion-imprinted polymer produced with the above-described monomers are illustrated. Combined with our recent works in salicylaldehyde Schiff bases functional monomer containing quaternary ammonium ion , the development trend of functional monomer is also prospected. Not only species of functional monomers requires further enriched,but also their function and performance have to be improved. Among those, the functional monomer of 5-chloro methyl salicylic aldehyde Schiff’s base modified with quaternary ammonium salt possesses shows strong hydrophilic properties and multi-functional characteristics,and a future research focus shall be the investigation on its performances in the application of functional monomers.%阐述了不饱和羧酸类（甲基丙烯酸、丙烯酸和乙烯基苯甲酸）、芳香杂环类（吡啶类、咪唑类和喹啉类）、水杨醛类希夫碱以及Salen配体等功能单体的性能、优点、用途等方面的研究进展，以及基于上述单体制备的离子印迹聚合物吸附特性和应用性能等，展望了离子印迹聚合物功能单体未来的发展方向：一是功能单体种类需要进一步丰富；二是其所具有的性能和功能等还有待于完善。其中，季铵盐化5-氯甲基水杨醛类希夫碱功能单体具有强亲水性能和多官能团特性，对其进行性能研究将会是探索此类功能单体在应用方面的热点内容之一。
