Abstract

The invention provides a method for preparation, characterization and performance test of graphene-graphene nanoribbon sponge in the field of chemistry. The method comprises the steps of (1) measuringthe concentrations of a graphene oxide (GO) solution and a graphene oxide nanoribbon (GONR) solution; (2) respectively extracting solutions with corresponding volumes into a mold according to a massratio of GO to GONR of 1:1, and uniformly stirring and mixing; (3) freezing the uniformly mixed GO-GONR solution in a cold well of a freeze dryer for 24 hours, vacuumizing, and starting freeze drying;(4) taking out the completely freeze-dried sample to obtain unreduced GO-GONR sponge at the moment; (5) putting the unreduced GO-GONR sponge into 90 DEG C hydrazine hydrate steam, reducing for 24 hours, cooling to the room temperature, taking out, putting into a vacuum drying oven, carrying out vacuum drying at the temperature of 100 DEG C, and cooling to the room temperature; and (6) characterizing the prepared sponge. The method is simple to operate.

Description

technical field

[0001] The invention belongs to the field of chemistry, and in particular relates to methods for the preparation, characterization and performance testing of graphene-graphene nanoribbon sponges. Background technique

[0002] Graphene nanosheets have a two-dimensional planar structure. After introducing one-dimensional (such as carbon nanotubes) or two-dimensional (such as molybdenum disulfide) nanomaterials and compounding them, due to the van der Waals force and π-π force between molecules For other reasons, these one-dimensional or two-dimensional nanomaterials will be adsorbed together with graphene nanosheets to form graphene composite nanosheets; by exerting the synergistic effect between various materials, graphene composite nanosheets have better Assembling it into a three-dimensional structure can obtain a multifunctional graphene composite sponge.

[0003] The Gaochao research group of Zhejiang University mixed multi-walled carbon nanotubes (MWCNTs...
