Description

technical field [0001] The invention relates to the field of airgel materials, in particular, to an airgel composite structural material and its preparation method and application, as well as structures or devices comprising the same. Background technique [0002] With the development of modern science and technology, the requirements for thermal insulation materials in many fields are getting higher and higher. Traditional thermal insulation materials such as inorganic fibers and organic foams can no longer meet the needs of modern industry. Therefore, a new development direction of modern industrial heat insulation materials - airgel composite heat insulation materials came into being, mainly because airgel has a high porosity, and its pores are nano-sized, which can effectively inhibit heat conduction and heat dissipation. Convection is currently the most ideal insulation material. [0003] SiO 2 Airgel has a special microstructure such as a three-dimensional nanopartic...
