▎ 摘　　要

NOVELTY - Preparation of multi-capsule porous graphene-based microrods, involves adding graphene oxide-silica aqueous solution or graphene oxide-silica functional filler aqueous solution to a coagulation bath, stirring to obtain a graphene oxide gel microrods slurry, hydrothermally reacting, cooling, filtering, carrying out solvent exchange, washing, drying to obtain reduced graphene oxide gel microrods laminated film, grinding the film, annealing, etching silica in the annealed product, filtering, washing, and drying. USE - Preparation of multi-capsule porous graphene-based microrods (claimed). ADVANTAGE - The method does not generate interface fusion self-assembly caused by interfacial tension and graphene oxide molecular hydrogen bond force, prevents generation of graphene-based crosslinked nonwoven fabric, and provides microrods with regulated and controlled size.
