摘要
在光照和引发剂的作用下,模板分子香豆素-3-羧酸、功能单体丙烯酰胺和交联剂乙二醇二甲基丙烯酸酯(EDMA)或三甲氧基丙烷三甲基丙烯酸(TR IM)在聚偏氟乙烯(PVDF)微孔滤膜表面聚合形成分子印迹聚合物复合膜.用高效液相色谱仪测定了分别以TR IM和EDMA为交联剂制备的分子印迹聚合物膜在不同溶剂中对混合底物的结合和渗透选择性.结果表明,以TR IM为交联剂的印迹膜对模板分子具有更高的结合和渗透选择性.另外,以乙腈或乙腈/水作为溶剂对分子印迹膜所作的实验和讨论有助于为从复杂样品中分离模板分子奠定理论和实验基础.
Using coumarin-3-carboxylic acid as template molecule, molecularly imprinted polymer composite membranes with supporting membrane （polyvinylidene fluoride） were prepared through in situ polymerization by UV-irradiation. The polymer membranes were synthesized by using acrylamide as the hydrogen-bonding monomer and ethyleneglycol dimethacrylate （EDMA） or tris（hydroxymethyl） propane trimethacrylate （ TRIM ） as cross linker. By comparing adsorption and permeation of the membranes with EDMA or TRIM as cross linker, and different solvents, the imprinted membranes with TRIM as the cross lingker and acetonitrile as solvent showed a higher adsorption capability, and the imprinted membranes with TRIM as the cross lingker and acetonitrile-water（ volume ratio 1：9 ） as the solvent showed higher permeation selectivity to the template.
