摘要

以水杨酸为模板分子，乙二醇二甲基丙烯酸酯为交联剂，采用乳液聚合法制备了水杨酸分子印迹聚合物微球（SMIP），采用紫外差示光谱分析了模板分子与功能单体的相互作用，以荧光分光光度计为检测手段，讨论了不同功能单体、模板分子与功能单体的摩尔比、交联剂用量、洗脱液类型等对SMIP吸附性能的影响，并进一步考察了SMIP的形貌和粒径分布。研究结果表明，以丙烯酰胺为功能单体合成的SMIP表现出较好的吸附性能，印迹因子可达1.61，而且微球呈单分散性，平均粒径约60 nm。

Abstract

The salicylic acid imprinted polymer microspheres (SMIP) were synthesized by emulsion polymerization using salicylic acid as template and ethylene glycol dimethacrylate as crosslinker.The interaction between the template and functional monomers was analyzed by UV subtractive spectroscopy.The effects of different kinds of functional monomers

molar ratio of template to functional monomer

dosage of crosslinker and elution solvent on the adsorption ability of SMIP were investigated by fluorescence spectrophotometry.The morphology and size distribution of SMIP were detected by SEM and Nanophox particle size analyzer.The results showed that the SMIP prepared by using acrylamide as functional monomer possessed higher adsorption ability than the blank polymer with the same chemical composition

and the imprinting factor reached 1.61.The particle size of SMIP was about 60 nm and the size distribution was narrow.
