1. Definition and core characteristics of aerogel sheets
Aerogel board is a lightweight, high-performance board made by composite technology with aerogel as the core substrate. According to different substrate types, aerogel boards can be divided into silica aerogel boards, graphene aerogel boards, polymer-based composite boards, etc., with excellent thermal insulation, flame retardancy and mechanical properties. Aerogel itself has extremely low density and a porosity of up to 80% to 99.8%, which makes it a lightweight and efficient thermal insulation material, widely used in construction, aerospace and other fields.
The key characteristics of aerogel boards include extremely low thermal conductivity and good flame retardancy, which give them superior performance in high temperature or high-risk environments. In addition, through fiber reinforcement and other technologies, the mechanical properties of aerogel boards have also been improved, enhancing compressive strength and toughness. With the continuous advancement of production technology, the application scope of aerogel boards is gradually expanding, becoming an indispensable and important material in high-tech products in many industries.
2. Preparation technology and process innovation
The preparation technology of aerogel sheets mainly involves the synthesis of aerogel substrates and the forming of composite sheets. With the advancement of science and technology, the synthesis method and preparation process of aerogels have been continuously optimized, bringing higher performance aerogel sheet materials.
The synthesis of aerogel substrates usually adopts the sol-gel method, which is a technology that uses metal oxide precursors in a solution to form a sol and converts it into an aerogel through a gelation process. In order to improve the performance of aerogels, the supercritical drying process has been widely optimized in recent years. Through supercritical drying, the solvent in the aerogel can be removed without destroying its microstructure, thereby avoiding shrinkage or cracking of the aerogel sheet during the drying process and maintaining its high porosity and low density. In addition, the application of 3D printing technology provides new possibilities for the high-precision structural design of aerogels. Using 3D printing, complex aerogel structures can be manufactured to meet the strict requirements of size and shape in different fields.
In the forming process of aerogel sheets, composite sheet technology is the key to improving their performance. Through fiber reinforcement strategies, the mechanical strength of aerogel sheets can be significantly improved, and their mechanical properties such as compression and tension can be improved. The addition of fibers not only improves the durability of aerogel boards, but also enhances their stability under high loads. On the other hand, multi-layer composite structure design has also been widely used in the research and development of aerogel boards. By combining aerogel layers with metal or polymer layers to form a multi-layer composite structure, the advantages of different materials can be fully utilized. The metal layer enhances the mechanical strength of the aerogel board, while the polymer layer improves its corrosion resistance and weather resistance. This design not only improves the comprehensive performance of aerogel boards, but also expands its application areas, such as high temperature protection, building insulation, etc.
In summary, the continuous innovation of the preparation technology of aerogel boards in synthesis process and composite molding technology has not only improved its thermal insulation, flame retardant and mechanical properties, but also broadened its application prospects in multiple industries. With the further development of these technologies, aerogel boards are expected to play an important role in more high-end application fields.

Building and Industrial Energy Saving
Aerogel boards show great application potential in the field of building and industrial energy saving. As an efficient thermal insulation material, aerogel boards can effectively replace traditional polystyrene boards and be used in building exterior wall insulation systems. This substitution not only significantly improves the energy efficiency of buildings and reduces the energy consumption of air conditioning and heating, but also, due to its excellent thermal insulation performance, can reduce building energy consumption by more than 30%, achieving significant energy-saving effects. In addition, aerogel boards are also widely used in the thermal insulation of pipelines and storage tanks in the petrochemical industry, especially in antifreeze and energy saving. Its extremely low thermal conductivity enables the equipment to maintain a constant temperature and avoid unnecessary energy loss, and it exhibits superior high temperature resistance and corrosion resistance in harsh environments, ensuring long-term stable operation.
Aerospace and Special Environments
In the field of aerospace, the application of aerogel boards is particularly important, especially in the design of thermal protection layers for spacecraft. The ultra-low thermal conductivity and high temperature tolerance of aerogel make it an ideal material for resisting extreme temperature gradients. When a spacecraft re-enters the atmosphere, the surface will be subjected to thousands of degrees of high temperature, and aerogel materials can effectively insulate and protect the spacecraft from damage. In addition, the application of aerogel boards in the insulation of deep-sea equipment has also received more and more attention. Deep-sea equipment needs to cope with extremely high pressure and corrosive environments, and the high strength, high pressure resistance and corrosion resistance of aerogel boards make them ideal insulation materials for deep-sea detectors, oil and gas exploration equipment, etc., ensuring the stable operation of equipment in extreme environments.
