▎ 摘　　要

NOVELTY - Preparing a graphene-carbon nanotube composite aerogel based on a bubble template method involves adding a surfactant to deionized water, stirring to produce bubble, and taking a layer of bubble agglomerate. The graphene oxide/carbon nanotube mixed solution is added to bubble agglomerate and stirred to obtain a uniform graphene oxide/carbon nanotube foam agglomerate. The obtained graphene oxide/carbon nanotube foam agglomerate is frozen and dried in a container to obtain a graphene oxide-carbon nanotube composite aerogel block. The obtained graphene oxide-carbon nanotube composite aerogel block is subjected to thermal reduction or chemical reduction to obtain a graphene-carbon nanotube composite aerogel. USE - Method for preparing a graphene-carbon nanotube composite aerogel based on a bubble template method. ADVANTAGE - The method enables to prepare a graphene-carbon nanotube composite aerogel based on a bubble template method, which has controllable porosity and pore size, low impurity content, certain mechanical strength, excellent hydrophobic and lipophilic property, simple preparation method and easy availability of raw material, and is environment-friendly.
