摘　　要：研究了聚(异丙基甲基丙烯酰胺)(PNIPMAM)@聚(N-异丙基丙烯酰胺)(PNIPAM)中空双壳微凝胶的合成过程.结合扫描电子显微镜、透射电子显微镜的形态学表征方法可简捷直观获得核壳结构微凝胶的粒径尺寸、三维立体及内部超微结构,进而揭示PNIPMAM@PNIPAM中空同心双壳结构微凝胶合成过程的形态学特征.The synthesis process of poly(N-isopropylmethacrylamide)@poly(N-isopropylacrylamide)(PNIPMAM@PNIPAM) hollow microgels has been studied. Using the morphological characterization method combined with scanning electron microscopy(SEM) and transmission electron microscopy(TEM), the particle size, threedimensional and internal ultrastructure of core-shell microgels in a simple and intuitive way can be obtained. Furthermore,the morphological characteristics of the synthesis process of PNIPMAM@PNIPAM hollow concentric double-shell microgels were revealed.
