Million times thinner than Paper but 200 times stronger than steel
*Graphene, a material made of a single layer of carbon atoms, has been praised for its extraordinary properties, including being 200 times stronger than steel, lighter than paper, and possessing exceptional mechanical and electrical characteristics.*
The researchers focused on polycrystalline graphene, which is produced using chemical vapor deposition and contains nanoscale defects. They developed the first statistical theory for the material's toughness, which refers to its resistance to fracture. While polycrystalline graphene does exhibit high strength, it was found to have relatively low toughness—lower than diamond and slightly higher than pure graphite.
