Characterization of Carbon Nanotubes

Carbon Nanotubes (CNTs) are one of the most remarkable materials discovered in the field of nanotechnology. Structurally, they are cylindrical allotropes of carbon with unique properties that arise from their nanoscale dimensions and graphitic carbon structure. Depending on how the graphene sheet is rolled, CNTs can exist as either single-walled carbon nanotubes (SWCNTs) or multi-walled carbon nanotubes (MWCNTs).

CNTs exhibit exceptional mechanical strength, electrical conductivity, thermal stability, and chemical resilience, making them highly valuable for a wide range of applications—including nanoelectronics, composite materials, energy storage, sensors, and biomedical devices. However, the performance of CNTs in these applications is highly dependent on their structural integrity, purity, size, defect levels, and chemical composition.

The characterization of carbon nanotubes refers to the systematic analysis and measurement of their physical, structural, chemical, thermal, and electrical properties.
