摘要
对SiO2纳米孔超级绝热材料的研究进展进行了概述,并对SiO2纳米孔超级绝热材料的孔、密度和导热系数等性能特征进行了描述;与热流在多孔材料中传播方式相似,纳米孔超级绝热材料的传热有对流、辐射和热传导三种基本方式;对 SiO2纳米孔超级绝热材料的制备方法及应用前景也进行介绍和分析。
The research advance on super thermal insulation material of nanohole SiO2 aerogel was introduced and the material characteristics of holes, density and coefficient of thermal conductivity were descirbed in the paper. Similar to the transmission method of heat flow in multihole material, the heat flow transmission methods of super thermal insulation material are convection, radiation and heat conduction. The preparation techniques and application prospect were also introduced in the paper.
