摘要
以Fe_3O_4@SiO_2为载体,吡嘧磺隆(PS)为模板分子,甲基丙烯酸(MAA)为功能单体,乙二醇二甲基丙烯酸酯(EDMA)为交联剂,通过表面印迹法制备磁性吡嘧磺隆分子印迹聚合物(MMIP),采用磁强计(VSM)、X-射线衍射(XRD)对其磁性能进行评价。结果表明,该磁性印迹聚合物具有良好的磁响应性。
A kind of magnetic molecularly imprinted polymer(MMIP) was synthesized by surface polymerization technique using pytazosulfuron -ethyl (PS) as template, methacrylic acid(MAA) as functional monomer and ethyle- neglycol dimethacrylate ( EDMA ) as cross - linker. The magnetic properties evaluation of the resulting composites were characterized by vibrating sample magnetometer(VSM) and X- ray diffraction(XRD). The results showed the MMIP has good magnetic responsiveness.
