摘 要: 分子印迹聚合物微球的粒径大小对其应用性能有很大影响,探讨了聚合溶剂的种类、体积、通气除氧时间和聚合时间对聚合物微球形貌和产量的影响。实验结果表明:在乙腈和氯仿中,可以制备出纳米级别的印迹聚合物微球。实验条件是通氮气除氧5 min,聚合24 h. 同时,利用环境扫描电镜对所制备的聚合物进行分析,可以看出:聚合物粒径均一,分布窄,有望提高分子印迹聚合物微球的应用性能和应用范围。
关 键 词: 功能材料;分子印迹;聚合物微球;沉淀聚合

Abstract: The shape and size of the molecularly imprinted polymer microspheres affect the application thereof, so in this paper the factors, including solution, volume, sparge time and polymerization time, which would affect the shape and yield, were discussed and optimized. The results showed that nanometric molecularly imprinted polymer microspheres were prepared in acetonitrile and chloroform by precipitation polymerization. The experimental condition was as follows, the sparge time was 5 min, and the polymerization time is 24 h. The shape and diameter of the obtained microspheres were evaluated by environmental scanning microscopy XL60. The results showed that the uniform, global nanometric microspheres were obtained. This study can enhance the application of molecularly imprinted microspheres in practice.
