Ultralight, compressible and multifunctional carbon aerogels based on natural tubular cellulose

Carbon aerogels feature ultralow density (1–2 mg cm ⁻³ ), high compressibility, high electrical conductivity (0.1 S cm ⁻¹ ), excellent fire-resistance and very high absorption capacity (147–292 g g ⁻¹ ) for organic liquids are prepared. Furthermore, the carbon aerogels can be easily endowed with various other functions, e.g. , magnetic responsivity and superhydrophobicity.
