▎ 摘  要

NOVELTY - Method for continuously producing graphene aerogel microspheres, involves (a) mixing graphene oxide with water to form a graphene oxide dispersion having a concentration of 3-20 mg/ml, mixing alkali metal hydroxide with the graphene oxide dispersion, and ultrasonically dispersing to obtain a graphene oxide liquid crystal solution, (b) placing the graphene oxide liquid crystal solution in a slurry supply device, applying pressure by a pressure supply device, and conveying the graphene oxide liquid crystal solution to a calcium chloride coagulation bath through a flow divider, and leaving still for 5-30 minutes to obtain graphene oxide microspheres, (c) placing the graphene oxide microspheres in sodium ascorbate solution, and reacting at 60-90 degrees C for 5-25 hours to obtain graphene wet gel microspheres, and (d) post-treating the graphene wet gel microspheres to obtain graphene aerogel microspheres. USE - The method is useful for continuously producing graphene aerogel microspheres.
