WEBJun 1, 2021 · Carbon nanotubes (CNTs) and their structure. CNTs were found by Sumiolijima [3] in 1991 and his first attempt to synthesizing multi-walled carbon nanotube was done by a simple arc evaporation method. CNTs are arranged in hexagon and Pentagon which are made up of carbon atoms with a diameter of 3–15 nm.
Carbon nanotube - Wikipedia
WEBA carbon nanotube (CNT) is a tube made of carbon with a diameter in the nanometre range . They are one of the allotropes of carbon. Single-walled carbon nanotubes (SWCNTs) have diameters around 0.5–2.0 nanometres, about 100,000 times smaller than the width of a human hair.
