▎ 摘 要
NOVELTY - Preparing a metal-containing graphene hybrid composite includes: combining an acid solution, a metal salt that contains a metal ion, and graphene oxide in order to reduce both the metal ion and the graphene oxide; and then depositing the reduced metal ion on the graphene oxide that has been reduced. USE - The method is useful for preparing a metal-containing graphene hybrid composite. ADVANTAGE - The method prepares highly conductive and highly elastic electrodes with high conductivity of 3012 S/cm and 322.8 S/cm at a strain of 35% using a metal-immersion graphene oxide reduced ink printed on a substrate provided with a high elasticity through an immersion process of a chemical elastomer polymer.
