Description

technical field

[0001] The invention relates to the technical field of nanometer materials, in particular to a carbon airgel, a preparation method thereof and a pressure sensor. Background technique

[0002] Airgel has the characteristics of large specific surface area, large porosity, low density, and low thermal conductivity. It has great application potential in the fields of electronics, aerospace, energy, chemical industry, industrial catalysis, and environmental protection. The most common aerogel is silica aerogel, which has been widely used in heat insulation, sound insulation and shock absorption. In recent years, carbon aerogels, especially graphene aerogels, have attracted extensive attention from researchers and industries. Graphene has high electrical conductivity (1×10 6 S / m), high modulus (1TPa), high strength (130GPa) and high specific surface area (2630m 2 / g) and other new two-dimensional materials with excellent properties, and graphene as the main body...
