NOVELTY - The preparation method of bubble-derived graphene porous film involves adding surfactant to deionized water and stirring to generate bubbles and surface layer agglomerates, adding graphene oxide solution to the bubble agglomerate template and stirring to obtain uniform graphene oxide foam agglomerate, blade coating the uniform mixture on a substrate by a doctor blade, placing blade coating film in a coagulation bath and curing, freeze-drying and peeling off to obtain graphene oxide porous film, and thermally reducing the film in an inert atmosphere. USE - The method is useful for preparing bubble-derived graphene porous film. ADVANTAGE - The method enables simple and economical preparation of bubble-derived graphene porous film with controllable pore size, and is suitable for large-scale industrial production.
