Graphene Can Stop a Speeding Bullet. When fired, the bullets flew through the air at 600 meters per second, according to the researchers). Upon impact, the sheets of grapheneabsorbed twice as much impact as Kevlar, the material commonly used in bullet-proof vests, and did tens time better than steel.
Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice. The name is a portmanteau of “graphite” and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.
