摘要:: 与传统的离子印迹技术相比，表面离子印迹技术利用螯合作用、静电作用等多种作用力将模板离子固定在功能单体中，再将功能单体接枝在载体表面，不仅可以获得更加均一的反应结合位点，而且解决了传统离子印迹材料制备过程中存在的包覆深、洗脱难的问题，进一步提高了表面离子印迹聚合物载体的选择性识别能力和选择性吸附能力。对近年来报道的表面铼离子印迹聚合物载体进行了分类阐述，主要包括硅材料、生物质材料和功能化纳米材料印迹复合膜等，指出了表面铼离子印迹聚合物在制备和应用过程中存在的一些不足，并对其未来的发展方向和应用前景进行了展望。

Abstract:: Compared with the traditional ion imprinting technology, surface ion imprinting technology uses various forces, such as chelation and electrostatic interactions, to fix the template ions in the functional monomer, and then graft the functional monomer on the surface of the carrier. Uniform reaction binding sites solve the problems of deep coating and difficult elution in the preparation process of traditional ion imprinted materials, and further improve the selective recognition ability and adsorption ability of the surface ion imprinted polymer carrier. The surface rhenium ion-imprinted polymer carriers reported in recent years are classified and explained, mainly including silicon materials, biomass materials and functional nanomaterials, etc. Some deficiencies in the preparation and application of surface rhenium ion-imprinted polymers are noted, and looked forward to its future development direction and application prospects.
