▎ 摘 要
NOVELTY - Preparing microporous graphene aerogel comprises (i) adding Nafion material into graphene oxide dispersion, dispersing and allowing to stand at 25-95 degrees C for 0.5-12 hours; (ii) adding diamine substance into the product obtained in the step (i) and carrying out heat treatment or hydrothermal treatment to obtain graphene hydrogel; and (iii) soaking the graphene hydrogel in water for hemodialysis, washing, lyophilizing and annealing. USE - The method is useful for preparing microporous graphene aerogel.
