Abstract

With the continuous development of human society, the emergence of energy conservation and consumption reduction is becoming increasingly critical. Although traditional insulation materials are widely used, their performance bottlenecks are gradually coming to the fore, such as insufficient durability, single performance and limited thermal insulation property. Therefore, the search for high-performance thermal insulation materials can provide a breakthrough solution. As an important thermal insulation technology, thermal insulating coatings have attracted considerable attention recently. SiO₂ aerogel, a porous material characterized by an internal network structure replete with gas and a solid appearance, accompanied by extremely low density, outstanding thermal insulation capabilities, high porosity, excellent thermal and chemical stability. In engineering, particularly within the realm of thermal insulation coatings, SiO₂ aerogel has been widely integrated into coatings with diverse functionalities, aiming to enhance energy utilization efficiency with substantial economic benefits. Its applications span across building construction, industrial sectors, freight storage, clothing, and aerospace. Notably, recent research has extensively investigated the combination of SiO₂ aerogel with other functional nanoparticles in composite thermal insulation coatings, which exhibited enhanced comprehensive properties, including flame retardancy, corrosion resistance, anti-aging, mechanical strength and adhesion, thereby ensuring more reliable performance in thermal insulation applications. This paper provides a comprehensive review of the preparation methods, properties, applications, and future trends of multifunctional SiO₂ aerogel based thermal insulation coatings, aiming to offer valuable insights to researchers and industry professionals. It is anticipated that this review will stimulate the scientific and engineering communities to further explore innovative SiO₂ aerogel based thermal insulation coatings through nano-technologies, thereby facilitating the industrial-scale production of these advanced materials.
