Uses of fullerenes and carbon nanotubes

Bonding, structure and the properties of matter • Structure and bonding of carbon

Key concepts

What you'll likely be quizzed about

  • Fullerenes consist of spherical or cage-like carbon molecules where each carbon atom bonds with three others, forming pentagons and hexagons.
  • Carbon nanotubes are cylindrical forms created by rolling graphene sheets.
  • Single-walled nanotubes (SWNTs) contain one tube, while multi-walled nanotubes (MWNTs) have several concentric layers.
  • The curvature in their sp2 bonding alters their electrical and mechanical properties compared to flat graphite.

Key notes

Important points to keep in mind

Fullerene shapes create unique electrical, thermal, and mechanical properties.

Functionalisation enhances solubility and biocompatibility but can alter intrinsic characteristics.

Effective nanotube dispersion and alignment are vital for superior composite performance.

Chirality affects whether nanotubes behave as metallic or semiconducting for electronics.

Toxicity, cost, and reproducibility challenge real-world applications.

High surface area of fullerenes and nanotubes aids adsorption, catalysis, and electrode functions.

Aggregation reduces effective surface area and degrades performance in composite and electrode materials.

Thermal conductivity along nanotubes aids in heat management when contact resistance is minimized.

Specific functional groups allow targeted delivery in drug applications.

Scalability and quality control are essential for mass market adoption.
