摘要
二氧化硅(SiO_2)气凝胶是通过使用气体来置换湿溶胶中的液体,从而得到一种结构可控的新型轻质纳米多孔固态材料。SiO_2气凝胶材料与其他保温隔热材料相比,具有较低的导热系数(≈0.013W/(m·K))和较高的透明性,在保温隔热领域中开发潜力巨大,有望替代传统的保温隔热材料.尽管气凝胶目前的成本高于传统的隔热材料,但是我们相信通过科学家和工程学家的不断努力,气凝胶的生产成本会被不断的降低,最终遍及世界各地.本文作者综述了SiO_2气凝胶材料在隔热领域的多种应用形式,介绍了目前国内外气凝胶公司研发产品情况以及实际应用案例。
Aerogel is a kind of synthetic porous material,in which the 1 iquid component of the gel is replaced with a gas.Aerogel has the translucent structure and remarkably lower thermal conductivity(≈0.013W/(m· K))than the other commercial insulating materials.Therefore,it is considered as one of the most promising thermal insulating materials.Although current cost of aerogel still remains higher compared to the conventional insulation materials,intensive eforts are made to reduce its manufacturing cost and hence enable it to become widespread all over the world.In this study,a comprehensive review on SiO_2 aerogel and its utilization in the field of thermal insulation are presented.
