NOVELTY - Preparing ultra-flexible multifunctional carbon aerogel, comprises (i) mixing every 10 ml graphene oxide solution having a concentration of 6 mg/ml with every 60 μm ethylenediamine, fully mixing, carrying out hydrothermal treatment and self-assembling to obtain hydrogel, and carrying out dialysis, pre-freezing, freeze-drying and thermal annealing to obtain graphene aerogel, (ii) mixing 100 ml ferrocene with 6 g 1,2-dichlorobenzene, carrying out chemical vapor deposition to obtain carbon nanotube aerogels, soaking the carbon nanotube aerogels in ethanol and applying uniaxial static load compression treatment, and naturally drying to obtain a densified carbon nanotube film, and (iii) spraying ethanol solution of graphene oxide as an adhesive on both sides of the graphene aerogel, and adhering the densified carbon nanotube film on both sides, and drying to obtain final product. USE - The ultra-flexible multifunctional carbon aerogel is useful in high-performance sensing and thermal management. ADVANTAGE - The method: prepares aerogel with excellent interfacial connection properties and structural stability by controls the thickness of graphene oxide adhesive, and enables synergistic enhancement of connected interfaces at the microscale. The aerogel: solves the key bottleneck problem between mechanics and functionality; and has excellent mechanical properties.
