In the past decade, interest in hollow silica particles has grown tremendously because of their applications in diverse fields such as thermal insulation, drug delivery, battery cathodes, catalysis, and functional coatings. Herein, we demonstrate a strategy to synthesize hybrid hollow silica particles having shells made of either polymer-silica or carbon-silica. Hybrid shells were characterized using electron microscopy. The effect of hybrid shell type on particle properties such as thermal and moisture absorption was also investigated.

在过去十年中，由于中空二氧化硅颗粒在隔热、药物递送、电池阴极、催化和功能涂层等不同领域的应用，人们对其兴趣大增。在此，我们展示了一种合成具有聚合物 - 二氧化硅或碳 - 二氧化硅壳层的混合中空二氧化硅颗粒的策略。使用电子显微镜对混合壳层进行了表征。还研究了混合壳层类型对颗粒性能（如热吸收和吸湿）的影响。
