【摘要】 本文以Fe₃O₄为磁响应性材料,分别以酪氨酸和苯丙氨酸为模板分子,以甲基丙烯酸、丙烯酰胺为功能单体,苯乙烯和二乙烯苯为聚合物母体组分,采用悬浮聚合制备了“动态”特性的印迹聚合物磁性复合微球,对其形态和磁性组分含量进行了表征;用液相色谱研究了分子印迹聚合物磁性复合微球对其模板分子的识别选择性。更多还原

【Abstract】 Amino acid imprinted Fe3O4/P(St-DVB) composite beads with magnetic susceptibility were prepared by suspension polymerization, using Fe3O4 as magnetically susceptible component, methacrylic acid and acrylamide as functional monomers. The morphology of the composite polymeric beads was observed by scanning electron microscope(SEM) . The recognition selectivity of the beads was investigated using tyrosine and phenylalanine as both templates and comparative molecules.更多还原
