CB0182 Carbon Nanotubes

Carbon Nanotubes Description

Single-Walled Carbon Nanotubes (SWCNTs):

SWCNTs consist of a single layer of carbon atoms rolled into a seamless cylindrical tube. They can have different diameters, which refer to the orientation of the hexagonal lattice with respect to the tube's axis. SWCNTs exhibit remarkable mechanical, electrical, and thermal properties due to their unique structure. They can act as semiconductors or conductors depending on their chirality, and they have potential applications in electronics, energy storage, and composite materials.

Multi-Walled Carbon Nanotubes (MWCNTs):

MWCNTs, as the name suggests, consist of multiple layers of graphene sheets rolled into concentric cylinders, like a Russian nesting doll. These tubes can have several walls, ranging from a few to tens of layers. MWCNTs also possess exceptional mechanical and electrical properties and are often used in various applications. They can be better conductors than SWCNTs, making them suitable for certain electronic and electromagnetic applications.

Both SWCNTs and MWCNTs have been extensively studied due to their unique properties and potential applications in a wide range of fields, including nanotechnology, materials science, electronics, medicine, and more. Researchers continue to explore their properties and applications, aiming to harness their extraordinary characteristics for various technological advancements.
