| 摘 要： | 针对聚合物核壳结构微球的结构特点,引入了同步辐射显微技术对微球的结构和组分进行了初步研究.利用同步辐射X射线显微成像技术对微球的内部形貌进行了表征,观测到壳层内壁大多呈光滑的圆弧,也有局部由若干个小圆弧连接组成;利用同步辐射红外显微光谱法对核内物质的组分进行了研究,结合X射线显微成像技术观察到的微球壳层内壁的高吸收现象,初步验证了微球内铁离子在辐照下被还原的化学反应过程,表明了利用聚合物核壳结构微球来开展化学反应研究是可行的.

| Abstract: | Considering the structural characteristics of polymeric core-shell microsphere,synchrotron radiation microscopy was introduced to study the structure and composition of the microsphere.The internal morphology of microspheres was characterized by using synchrotron radiation X-ray microscopy.It was observed that most inner walls of microspheres are smooth circles,while a few are composed of a number of small circles.In combination of the high absorption phenomenon at the inner wall of the microsphere observed... |
