The detection range of aerogel covers many types, among which graphene aerogel has attracted much attention due to its unique structure and excellent performance. Graphene aerogel has excellent electrical and thermal conductivity and has broad application prospects in the field of electronic devices and energy. Nanoaerogel, with its extremely small size and special physical properties, provides an important material basis for the research of the microcosmic world and the development of nanotechnology. Cellulose aerogel is derived from natural cellulose and has good biocompatibility and degradability, showing great potential in biomedicine and environmental protection fields.

     All-carbon aerogel has very high strength and stability, and has important application value in the field of aerospace and other demanding materials. Aerogel insulation material with its excellent insulation performance, widely used in construction, industry and other fields, effectively reduce energy consumption. By combining with other materials, the properties of aerogel composites are complemented and optimized, and their application range is expanded. Solid aerogels play a key role in structural materials, providing solid support for a variety of engineering applications.

     Silica aerogel is an important member of the aerogel family, which has good chemical and thermal stability. Due to the unique properties of chitosan, chitosan aerogel has a unique application advantage in biomedicine and tissue engineering. Bioaerogel is closely related to life science and opens up a new way for the research and development of biological materials.

     The testing items of aerogel are rich and varied, and component detection is the basis, which can accurately analyze the content of various elements and compounds in aerogel, and provide key data for the performance evaluation of materials. The bulk density test helps to understand the packing tightness of the aerogel, and the quantitative test can accurately determine the aerogel content. DSC detection can reveal changes in the thermal properties of aerogels, and fire resistance detection is essential to evaluate their safety in high temperature environments.


     The bending failure load test can measure the structural strength of aerogel. BET characterization test is used to analyze the specific surface area and pore structure of aerogel. Transmission electron microscopy (TEM) can observe the microstructure of aerogel in depth, and radiation resistance test can investigate its stability under radiation environment. Thermogravimetric analysis can understand the mass change of aerogel at different temperatures, and infrared spectral characterization helps to determine its chemical composition and functional groups. SEM morphology detection can directly show the surface morphology of aerogel, and density detection and porosity detection are interrelated to reflect the physical structure characteristics of aerogel.

     Thermal conductivity tests evaluate the heat transfer performance of aerogels, while flexibility and rigidity tests focus on their mechanical properties. Thermal conductivity detection is an important index to measure the thermal insulation ability, and the thermal insulation ability detection is directly related to the application effect of aerogel in the field of thermal insulation. Vibration mass loss rate test reflects the stability of aerogel under vibration condition, and water resistance test examines its performance in wet environment. Compressive strength test at room temperature evaluates the compression resistance of aerogel, corrosion performance test measures its durability in corrosive environments, compressive resilience test reflects the elastic recovery ability of aerogel, specific surface area test reveals its surface activity, tensile strength test examines its tensile properties, direct deviation test and flatness test focus on the geometric accuracy of aerogel. Critical load testing is used to assess its carrying capacity.

     The standard for aerogel testing is GB/T 34336-2017 nanopore aerogel composite insulation products, which provides specifications and guidance for the testing of aerogel, ensures the accuracy and reliability of the test results, and helps promote the healthy development and wide application of the aerogel industry.
