Abstract

The invention discloses a method for preparing a three-dimensional porous graphene material by solution. The method comprises the following steps of: immersing a three-dimensional porous template into a graphene oxide solution, and then depositing the graphene oxide on the template to realize three-dimensional assembling of the graphene oxide on the template, and then preparing the three-dimensional porous graphene material containing the template by reduction; removing the template from the three-dimensional porous graphene material containing the template, and then washing to obtain the three-dimensional porous graphene material. The aperture of the three-dimensional porous graphene material can be regulated and controlled by using the templates with different apertures the material prepared by the invention has the advantages of low density, high specific surface area, high heat conductivity, high-temperature resistance, and corrosion resistance; the preparation method is economical and simple and suitable for large-scale production. And the prepared material is applicable to aspects such as catalytic carriers, preparation of flexible conductors, and stretchable electronics.
