Part 2 - Key Facts:

Graphene

• What Is It?

  • A single layer of graphite, one atom thick, with a hexagonal structure.

• Properties:

  • Strong and Lightweight: Its strength makes it ideal for reinforcing materials in composites.

  • Conducts Electricity: Due to delocalised electrons, making it useful in electronics like flexible screens and high-speed circuits.

  • Transparent: Can be used in touch screens and solar cells.

Fullerenes

• What Are They?

  • Hollow molecules of carbon atoms arranged in hexagonal rings. Some may also contain rings of 5 or 7 atoms.

• Types of Fullerenes:

  • Buckminsterfullerene (C60):

    • A spherical molecule resembling a football.

    • Used in drug delivery, as it can trap other molecules inside.

  • Carbon Nanotubes:

    • Cylindrical fullerenes with an extremely high length-to-diameter ratio.

    • Properties:

      • High Strength: Useful in lightweight materials.

      • Conductive: Perfect for electronics and nanotechnology.

      • Flexible and Heat Resistant: Suitable for high-performance devices.
