Multi-Walled Carbon Nanotubes (MWNTs): Properties, Synthesis, and Applications Introduction Multi-Walled Carbon Nanotubes (MWNTs) are a type of carbon nanotube characterized by multiple concentric cylindrical layers of graphene. Unlike Single-Walled Carbon Nanotubes (SWNTs), which consist of a single graphene layer, MWNTs have several layers, providing them with unique properties and a broad range of applications. Their...
