气凝胶微球的制备和应用

Preparation and Applications of Aerogel Microspheres

与传统的块状气凝胶不同,气凝胶微球是一种具有独特结构的新材料。它既由纳米级材料构建,又有微米级尺寸,同时还具备气凝胶特有的热、声、光、电性质和复杂的三维网络拓扑结构,在生物医药、环境修复、功能性载体、能源存储和转化等领域具有广泛的应用潜力。近年来,国内外关于气凝胶微球的研究进展迅速,但关于气凝胶微球的综述还没有报道。本文结合气凝胶微球领域最新的研究进展,从气凝胶微球的制备方法、种类以及不同种类的气凝胶微球在环境、医药、能源领域的应用等方面进行了综述。

Different from conventional aerogel monoliths, aerogel microspheres are new kind of aerogel materials with unique structures. Aerogel microspheres has micron size and is composed of nanoscale materials with the aerogel-featured unique heat, sound, light, electrical properties as well as complex three-dimensional topology networks, which means they have a wide application potential in the fields such as biological medicine, environmental remediation, functional carrier, energy storage and conversion, etc. In recent years, the research progress of aerogel microspheres has been rapidly growing,, however, there is rare review on aerogel microspheres. In this paper, based on the latest research progress in the fields of aerogel microspheres, we made a brief review on preparation methods, different types and applications in medicine, environment, energy fields of aerogel microspheres.
