摘要
金属离子印迹聚合物是以金属离子为模板,在静电、络合、配位等作用下与功能单体相互作用,在一定条件下交联聚合后去除模板离子,获得具有许多特定形状和大小的孔穴的聚合物。由于离子印迹聚合物具有与模板离子大小、电荷和空间结构相匹配的稳定空腔,对模板离子有较高的特异识别性和亲和性,在离子分离、富集以及传感识别等领域有着广阔的应用前景。在金属表面离子印迹材料的制备过程中,载体材料的选择不仅在材料稳定性方面起着至关重要的作用,而且对重金属的特异识别性有一定的协同作用。本文对近年来硅基类、碳基类、磁性类、树脂基类、纤维类为载体材料的离子印迹材料进行了简要的综述,为表面离子印迹材料的研究和应用提供参考。
Ion imprinted polymers,which have many cavities with special shapes and sizes,are prepared by copolymerization of functional monomer and cross-linking agent in the presence of template metal ions through coordination,electrostatic or complexation interactions.It was widely used in ion separation,enrichment and sensing identification areas because the ion-imprinted polymers have stable cavities matched the size,charge and spatial structure for template ions,and have high specificity and affinity for template ions.During the process of surface ion-imprinted polymers preparation,the choice of carrier not only played a vital role in the stability of the material,but also had a certain synergistic effect on the specific identification of heavy metal ions.In the paper,ion-imprinted polymers based on silicon-based,carbon-based,magnetic,resin-based,and fiber-based are reviewed in recent years,which would provide a reference for the research and application of surface ion-imprinted polymers.
