▎ 摘　　要

NOVELTY - The method involves manufacturing a three-dimensional porous graphene assembly. Graphene oxide is dispersed into de-ionized water to obtain concentration of graphene oxide dispersion liquid. Hydrothermal reaction process is performed to obtain graphene hydrogel of a three-dimensional porous structure. Graphene hydrogel freezing and drying to obtain graphene aerogel. The graphene aerogel dispersed in water solution to prepare functional graphene slurry. A graphene test paper electrode is connected with a three-electrode system by an assembling part. The graphene test paper electrode is provided with a working electrode, a printing carbon and a counter electrode. USE - Electrochemical detection graphene electrode printing paper manufacturing method. ADVANTAGE - The method enables realizing electrochemical detection graphene electrode printing paper manufacturing process in an accurate and practicable manner. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a three-dimensional porous graphene assembly.
