"Rebar graphene" foam supports 3,000 times its own weight
MIT scientists recently developed a 3D version that's 10 times stronger than steel but a fraction of the density, and now a team at Rice University has used carbon nanotubes to reinforce graphene foam. The resulting 3D material can be molded into any shape and supports 3,000 times its own weight before springing back to its original height.
Named for the rebars (reinforcing bars) commonly used to strengthen concrete, Rice's "rebar graphene" is built around carbon nanotubes with several concentric layers. In previous work the team had created three-dimensional graphene foam, and having already used the nanotubes to reinforce regular old 2D graphene, it made sense to combine the two.
"We developed graphene foam, but it wasn't tough enough for the kind of applications we had in mind, so using carbon nanotubes to reinforce it was a natural next step," says James Tour, lead researcher on the study.
