简述了表面分子印迹聚合物载体研究的最新进展。根据载体种类以及表面修饰方法的不同,分别介绍了以无机材料为载体和以壳聚糖为基质的表面分子印迹技术,并对表面分子印迹聚合物载体的发展前景进行了展望。对无机材料的表面修饰主要通过引入烷基化试剂的功能基团(如氨基、苄基等),再通过分子印迹的方法制备出理想的表面分子印迹聚合物;而对壳聚糖的修饰主要通过各种交联方法,从而获得单一基质载体或者壳聚糖杂化材料载体。文中指出,与传统方法相比,新型材料的吸附性能优良、回收利用率高、颗粒均一。但是,该材料制备过程中的微观行为模式以及功能单体同目标分子的成键规律等还有待进一步研究。
The advance in surface molecularly imprinted polymer carriers is reviewed.In this paper,the surface molecularly imprinting technique with inorganic material and chitosan as the carriers is introduced respectively according to different types of carriers and surface modification methods,and the development prospect of the carriers is also presented.The surface modification of inorganic materials is mainly achieved by introduction of the functional groups(such as the amino group,the benzyl group,etc)of the alkylating agents.Then,the polymers are prepared by the surface molecularly imprinted technique.However,the modification of chitosan is completed by a variety of cross-linking methods in order to obtain a single matrix or a hybrid material as the carrier.Compared with traditional methods,the novel material has an excellent performance of good adsorption ability,high recycling rate and uniform particles.Nevertheless,further research is needed to study the micro behavior patterns during the preparation of polymers as well as the bonding rules between the functional monomer and the target molecule.
