ESCA results show that silica is coated on surface of the polymeric microspheres. SEM analysis reveals that when water was used as a solvent, uniform silica coating on the surface of organic microsphere can be obtained, and when the reactive time is 10 minutes, an uniform coating layer can be prepared. But when tetrachloroethylene was used as a reactive solvent, an inhomogeneous silica coating is found on the organic microspheres.
由化学分析电子光谱仪纵深分析可以得到,矽的前驱物是藉由披覆方式附著在有机微球表面;SEM分析发现以水为溶剂所合成出之披覆有二氧化矽的有机微球表面呈现均匀披覆效果,并且当反应时间为10min时表面均匀披覆效果最好;而以四氯乙烯为溶剂的系统所合成之微球则呈现不均匀披覆。
