multiwalled carbon nanotube

Multi-walled carbon nanotubes (MWNTs) are nanoscale hollow tubes made of carbon atoms, forming concentric cylinders with diameters typically ranging from about 1 nanometer to tens of nanometers and lengths up to millimeters. They are a type of fullerene, a class of carbon molecules that includes spherical structures like buckyballs.12

MWNTs are synthesized using methods such as arc discharge, laser ablation, and chemical vapor deposition (CVD). These nanotubes possess unique properties, including exceptional tensile strength and electrical conductivity, making them promising for applications in nanotechnology, electronics, and advanced materials. However, concerns exist regarding their potential health risks, as research suggests they may pose dangers similar to asbestos if inhaled.12
