Beschreibung
Zusammenfassung:	The invention discloses a preparation method and application of three-dimensional graphene nano-scroll aerogel, and belongs to the technical field of graphene material preparation. The preparation method comprises the following steps: firstly, freeze-drying a graphene oxide solution to obtain graphene oxide aerogel; in a plasma environment, the plasma radio frequency power is set to be 250 W or above, the processes of reduction, stripping and curling of the graphene oxide sheet layer can be achieved within one second, and the aerogel material rich in the graphene nano-roll structure is obtained. The method has the characteristics of high efficiency, mild reaction conditions, low cost and environmental protection, and is easier to realize large-scale production. The graphene nano-scroll aerogel prepared by the method can be used as an electrode material in a capacitive deionization device, and salt ions in seawater are efficiently removed by virtue of an ultrahigh specific surface area and a rich pore structur
