Advanced materials (Deerfield Beach, Fla.), 2015•europepmc.orgProgrammable photoactuation enabled by graphene: Graphene sheets aligned in liquid
crystalline elastomers are capable of absorbing near-infrared light. They thereafter act as
nanoheaters and provide thermally conductive pathways to trigger the nematic-to-isotropic
transition of elastomers, leading to macroscopic mechanical deformation of
nanocomposites. Large strain, high actuation force, high initial sensitivity, fast reversible
response, and long cyclability are concurrently achieved in nanocomposites.
