Single Walled Carbon Nanotubes - 308068-56-6

Key Functions: Industrial / Manufacturing

CNTs are a group of nanomaterials consisting of only one or several hexagonal graphite sheets of carbon atoms rolled into tubes. They have very high aspect ratios with diameters lower than about 100 nm (0.000001 mm) and lengths that can reach several hundred micrometers. CNTs fundamentally fall into two classes: single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs). Despite the obvious commonality, SWCNTs and MWCNTs have significantly different physical properties from each other because of their structural differences. The most important feature that distinguishes SWCNTs is that the wall of the nanotube consists of the only one graphene layer. The length of a C–C bond in a graphene sheet of SWCNT is 0.142 nm. The CAS number is assigned to carbon nanotubes in general regardless of the types (single, double or multi wall) (IARC 2017).
