Synthesis and processing of graphene hydrogels for electronics applications†
Abstract
Synthesis of a graphene hydrogel, in which the elastic modulus can be changed from ∼10 to ∼105 Pa and the electrical conductivity can be controlled in a range from ∼0.01 to ∼6 S cm−1 by carefully adjusting the graphene content, allowing for direct processing and patterning of graphene for many electrical applications.
