▎ 摘　　要

NOVELTY - Preparing three-dimensional graphene material with high conductivity and high elasticity comprises (a) preparing the three dimensional graphene material by hydrothermal reduction method, (b) placing metal aluminum powder and the three-layer graphene material respectively in the low temperature area and the high temperature area of the dual-area vacuum furnace, introducing a certain amount of water vapor and heating at the same time, setting the temperature of the low-temperature area is 150-300?? C and the temperature in the high-temporal area is 700-900?? C, and keeping the temperature for 2-6 hours to obtain the product. USE - Preparation method of high-conductivity, high-elasticity three-dimensional graphene material used in sensor, energy storage and conversion, catalytic and environmental adsorbent. ADVANTAGE - The method provides high-conductivity, high-elasticity three-dimensional graphene material with excellent electrical and mechanical properties.
