Double walled Carbon Nanotubes (unpurified)

Introduction:

Double walled carbon nanotubes (DWCNTs) consist of two concentric layers of carbon nanotubes, offering unique structural and electronic properties that differentiate them from single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs). This unique architecture enhances their mechanical strength, electrical conductivity, and thermal stability, making DWCNTs suitable for a wide range of applications. Their properties are influenced by the interactions between the two walls, which can lead to improved performance in various fields.
