NOVELTY - The preparation of aminated carbon nanotube-graphene aerogel, involves uniformly dispersing graphene oxide powder to form graphene oxide solution, adding graphene oxide solution to carbon nanotubes in mass ratio 1:0.5 to 1:4, stirring, obtaining homogeneous solution of carbon nanotube-graphene oxide composite solution, adding ethylenediamine and aqueous ammonia to resulting solution, stirring, sealing mixed solution, heating at constant temperature, washing and cleaning reaction product, lyophilizing to obtain aerogel, freeze-drying, and obtaining hydrogel composite. USE - Preparation of aminated carbon nanotube-graphene aerogel (claimed). ADVANTAGE - The method enables preparation of aminated carbon nanotube-graphene aerogel by simple process, improves composite material absorbing performance for gaseous state formaldehyde, and the prepared aerogel has excellent performance and is easy to collect and suitable for large scale production.
