DOI: 10.1002/adma.202200444
Abstract: Typically, solid materials exhibit transverse contraction in response to stretching in the orthogonal direction and transverse expansion under compression conditions. However, when flexible graphene nanosheets are assembled into three-dimensional (3D) porous architecture, the orientation arrangement… read more here.
