CB0182 Carbon (C) Nanotubes

Carbon Nanotubes Description

Single-Walled Carbon Nanotubes (SWCNTs):

SWCNTs consist of a single layer of carbon atoms rolled into a cylindrical tube. They are produced in various diameters determined by the orientation of the hexagonal carbon lattice relative to the tube axis. SWCNTs exhibit measurable mechanical, electrical and thermal properties. According to their chirality, they may operate as semiconductors or conductors and have potential applications in electronics, energy storage and composite materials.

Multi-Walled Carbon Nanotubes (MWCNTs):

MWCNTs comprise several layers of graphene sheets rolled into concentric cylinders. The tubes may consist of as few as two layers or extend to several dozen layers. MWCNTs demonstrate quantifiable mechanical and electrical characteristics and are frequently used in multiple applications. They tend to conduct electricity more effectively than SWCNTs and are appropriate for specific electronic and electromagnetic applications.

Both SWCNTs and MWCNTs have been extensively studied owing to their distinct properties and potential applications in domains such as nanotechnology, materials science, electronics and medicine. Researchers continue to investigate their properties and applications with the aim of utilising their defined characteristics for various technological advancements.
