▎ 摘  要

NOVELTY - Triggering self-propagating reduction-exfoliation process of graphene oxide in a porous material comprising graphene oxide to increase the total electric conductivity and the specific surface area of the porous material characterized in that the initial electric plasma is generated in the adjacent part and only partly in the inside part of the total volume of the reduced-exfoliated porous material, where to generate the initial electric plasma the temperature of a working gas is less than 400° C, the pressure of the working gas is higher than 10 kPa, the speed of the working gas is less than 0.1 mxs1, the temperature of the total volume of the porous material is less than 200° C, and at the same time the Laplacian electric field in the volume of the porous material not intersected by the initial plasma is less than the critical electric field of the working gas, and the working gas contains less than 5 % of hydrogen gas. USE - The method is useful for: triggering self-propagating reduction-exfoliation process of graphene oxide in porous material. ADVANTAGE - The method provides fast and industrial mass production of self-propagating process of reduction-exfoliation in porous material.
