Carbon nanotube materials have the advantages of light weight and high strength, and are widely used in the production of bicycles, rackets and other products
Asbestos is a carcinogen confirmed by the international cancer organization, and carbon nanotubes have some similarities with asbestos in chemical molecular structure
 However, recent studies have found that workers who have been engaged in the production of carbon nanotubes for a long time or use this material to make other products may cause cancer by inhaling carbon nanotubes
