摘要
二氧化硅气凝胶是一种具有高孔隙率、低密度以及低热导率等特性的纳米多孔材料,在保温隔热、环境净化以及生命医学等领域应用广泛。文章对比分析了不同硅源基气凝胶的性能差异,以及改善二氧化硅力学性能的方法,如纤维和聚合物增强二氧化硅气凝胶以及制备柔性二氧化硅气凝胶,介绍了其在不同领域中的应用,并对其未来的发展趋势进行了展望。
Silica aerogel is a kind of nano porous material with high porosity,low density and low thermal conductivity,which is widely used in thermal insulation,environmental purification,life medicine and other fields.This paper compares and analyzes the performance differences of different silicon source based aerogels,as well as the methods to improve the mechanical properties of silica,such as fiber and polymer reinforced silica aerogels and the preparation of flexible silica aerogels,introduces its application in different fields,and prospects its future development trend.
