5. Aerogel applications

Due to their very high specific surface area and porosity properties, aerogels have found many potential applications in various fields such as insulation (thermal and acoustic), catalysts, aeronautics, optics, energy storage, nuclear power, but also in life and environmental sciences. In what follows, we'll show just a few examples of aerogels and their applications. These examples are not exhaustive .

Potential applications are numerous, as they take advantage of the different physical and chemical properties of these materials, such as :

• their high porosity (lightness, possibility of doping);
