▎ 摘　　要

NOVELTY - Preparation of ultra-light, super-elastic, high-conductivity three-dimensional porous graphene material involves (i) adding glycolic acid as a crosslinking agent to graphene oxide solution to obtain a mixed solution, (ii) hydrothermally reacting the obtained mixed solution at 100-150degrees Celsius, placing in a hydroalcoholic solution, and (iii) freeze-drying. USE - Preparation of ultra-light, super-elastic, high-conductivity three-dimensional porous graphene material (claimed). ADVANTAGE - The method provides the three-dimensional porous graphene material with ultra-light, super-elasticity and high conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for ultra-light, super-elastic, and highly conductive three-dimensional porous graphene material, which has density of 4.3-25.3 mg/cm3, elasticity modulus of 13.7-125.1 kPa, volume of 6.5-300 cm3, and conductivity of 32.3-98.1 S/m.
