▎ 摘　　要

Synthesis of a graphene hydrogel, in which the elastic modulus can be changed from similar to 10 to similar to 10(5) Pa and the electrical conductivity can be controlled in a range from similar to 0.01 to similar to 6 S cm(-1) by carefully adjusting the graphene content, allowing for direct processing and patterning of graphene for many electrical applications.
