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

Abstract

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, <italic>e.g.</italic>, magnetic responsivity and superhydrophobicity.
