Q. This material consists of a single layer of carbon atoms arranged in a two-dimensional hexagonal honeycomb lattice. Known for its performance metrics, it can stretch by up to 20-25% of its length, conducts electricity better than copper, and exhibits mechanical tensile strength roughly 200 times stronger than steel by weight. Identify this material:
Answer: B
Notes:
Explanation:
- Graphene is a versatile nanomaterial. Its unique single-atom-thick 2D structure gives it exceptional electrical conductivity, thermal performance, elasticity, and mechanical strength.
- These properties make it useful for an array of advanced applications, from high-sensitivity environmental sensors and high-density electric vehicle batteries to water desalination filters.
