Document Type and Number:
WIPO Patent Application WO/2016/037565
Kind Code:
A1
Abstract:
Disclosed are a graphene hydrogel and a graphene aerogel as well as preparation methods therefor and applications thereof. The preparation method for a graphene hydrogel in the present invention comprises: (1) uniformly mixing a graphene oxide dispersion and a water-soluble reducing agent to obtain a graphene oxide mixed liquid; and (2) irradiating the graphene oxide mixed liquid by using high-energy rays, so as to perform an irradiation reaction to obtain the graphene hydrogel. The preparation method for a graphene aerogel in the present invention comprises: performing freeze-drying or supercritical carbon dioxide drying on the graphene hydrogel. The present invention also provides an application of the graphene aerogel in adsorbing an organic solvent. In the present invention, an irradiation method is used to prepare a graphene aerogel; the preparation method is simple in operation, is green and environmentally friendly, and has mild reaction conditions; and the prepared graphene aerogel is of a porous structure with large pores, has a uniform structure, and has great application value.
