▎ 摘　　要

NOVELTY - The method involves (S101) coating a graphene ink on a mesh-shaped substrate by a spray process; (S102) drying the graphene ink-coated substrate by heat treatment or microwave; #(S103) firstly pressing the dried substrate by a high-temperature roll-press process; and (S104) secondly pressing the first pressurized substrate by a low-temperature roll-press process. USE - Method for manufacturing a graphene-coated substrate. ADVANTAGE - The method ensures that the graphene-coated substrate is coated by a spray process using graphene ink, and then the graphene-coated substrate is pressed by a roll-press process, so that the prepared graphene-coated substrate exhibits excellent performance not only in horizontal electrical conductivity, but also in vertical electrical conductivity.
