摘要: 以苯胺和二甲基苯胺为模板分子、甲基丙烯酸(MAA)为功能单体、三羟甲基丙烷三丙烯酸酯(TRIM)为交联单体、Fe3O4为磁性组分,采用悬浮聚合法制备了磁性分子印迹聚合物微球(MMIPMs)。结果表明,改性Fe3O4微粒在MMIPMs中分散较好,MMIPMs在水性介质中对模板分子的选择吸附性较差,但在有机介质中有较好的选择吸附性。Abstract: Magnetic molecularly imprinted polymer microspheres(MMIPMs) were prepared by suspension polymerization,using trimethylolpropane triacrylate(TRIM),methacrylic acid(MAA) and surface modified Fe_3O_4 as crosslinker,functional monomer and magnetic component,r
