Abstract：
Aerogel is a kind of typical nanoporous material with consecutive 3D network. Because of its low density, high specific surface area, high porosity, low coefficient of thermal conductivity characteristics, aerogel has a broad prospect of application in many fields, such as thermal, optical, electrical, acoustic and so on. In a wide variety of aerogel, silica aerogel is the most widely used currently. In this paper, oxide aerogel, carbon aerogel and carbide aerogel were introduced in detail based on the types of aerogel.
