Carbon nanotubes (CNTs) are the most well-known and widely studied type, consisting of rolled-up sheets of graphene with diameters ranging from about 1 to tens of nanometers and lengths up to millimeters.<ref name = "Maruyama_2022">{{cite journal | vauthors = Maruyama S, Arnold MS, Krupke R, Peng LM | title = Physics and applications of nanotubes. | journal = Journal of Applied Physics | date = February 2022 | volume = 131 | issue = 8 | doi = 10.1063/5.0087075 }}</ref><ref name = "Ren_2024">{{cite encyclopedia | vauthors = Ren G | title = Carbon nanotube | encyclopedia = Encyclopedia Britannica | date = September 2024 | url = https://www.britannica.com/science/carbon-nanotube }}</ref> These structures exhibit remarkable physical, chemical, and electrical properties, including high tensile strength, excellent thermal and electrical conductivity, and unique quantum effects due to their one-dimensional nature.<ref name = "Ren_2024" /> Nanotubes can be classified into two main categories: single-walled nanotubes (SWNTs) and multi-walled nanotubes (MWNTs), each with distinct characteristics and potential applications. Since their discovery in 1991, nanotubes have been the subject of intense research and development, with promising applications in fields such as electronics, materials science, energy storage, and medicine.<ref name = "Maruyama_2022" /><ref>{{cite web | title = Current and Potential Applications of Carbon Nanotubes | vauthors = Reidel H | date = March 2017 | work = PreScouter | url = https://www.prescouter.com/2017/03/applications-carbon-nanotubes/ }}</ref>
