Carbon nanotubes (CNTs) are hollow cylindrical tubes formed by rolling a sheet of carbon atoms arranged in a hexagonal ring, as in a sheet of graphite, either in monolayer (single walled nanotube, SWCNT) or multilayer (multi-walled nanotube, MWCNT) form. Their diameter may range from 0.7 (SWCNT) to 50 naometers …
