| 摘 要： | 通过可逆加成-断裂链转移(RAFT)自由基反应,在球形硅胶表面制备了分子印迹纳米膜.茶碱吸附实验显示,与对照组的杂化球形硅胶相比,分子印迹纳米膜杂化球形硅胶对茶碱具有更高的吸附结合能力.利用RAFT所具有的活性/可控的特点,通过改变实验条件控制分子印迹纳米膜在硅胶表面的生长,可以得到较厚的分子印迹纳米膜以获得较好的吸附量,也可以得到较薄的分子印迹纳米膜以获得较好的吸附效率.

| Abstract: | In this study,molecularly imprinted polymer(MIP) nano-films for theophylline were prepared on the surface of silica microspheres through reversible addition-fragmentation chain transfer(RAFT) polymerization.The theophylline binding analysis showed that,compared with the control polymer nano-films hybridizing silica microspheres,the MIP nano-films hybridizing silica microspheres had higher affinity for theophylline.Utilizing the controllable nature of RAFT,we could control the growth of MIP nano-films on the silica microspheres.Thus it is possible to tailor the resulting microspheres to have high capacities by growing thicker MIP nano-films or higher binding efficiency by growing thinner MIP nano-films. |
