NOVELTY - Preparing bubble-derived graphene-carbon nano-tubecomposite porous film involves adding surfactant to deionized water, then stirring to generate bubbles, and taking layer of bubble agglomerates to obtain mixed solution of graphene oxide and carbon nanotubes. The obtained mixed solution of graphene oxide and carbon nanotubes is added bubble agglomerate and stirring to obtain uniform graphene oxide/carbon nanotube foam agglomerate. The uniform graphene oxide/carbon nanotube foam agglomerate is scraped on a substrate by a doctor blade to form film, which is freeze-dried, and peeled off to obtain graphene oxide-carbon nanotube composite porous film. The film is then thermally reduced in an inert atmosphere to obtain independently self-supporting graphene-carbon nanotube composite porous film. USE - Method for preparing bubble-derived graphene-carbon nano-tubecomposite porous film. ADVANTAGE - The method enables to prepare bubble-derived graphene-carbon nano-tube composite porous film, which has controllable aperture size, simple device operation, low preparation cost, and further amplified to batch large scale preparation.
