Crumpled graphene and rubber make artificial muscle

ERJ staff report (BC)

Durham, North Carolina – Despite many extraordinary properties, graphene (a one-atom thick carbon lattice structure) has a stickiness which makes it difficult to flatten out once crumpled.

Engineers at Duke University have found that by attaching graphene to an elastic polymer film, they can crumple and then unfold the material reversibly, lending it to a range of applications.

One “soft” version of the Duke material acts like an artificial muscle. When an electic potential is applied, the material expands, and when the potential is…
