Carbon nanotube reinforced graphene is twice as tear resistant
Fracture-resistant “rebar graphene” is more than twice as tough as pristine graphene. Rebar graphene, developed by the Rice lab of chemist James Tour in 2014, uses carbon nanotubes for reinforcement. Graphene is a one-atom-thick sheet of carbon. On the two-dimensional scale, the material is stronger than steel, but because graphene is so thin, it is …
