• En química, denomínanse nanotubos a estruturas
  tubulares cuxo diámetro é da orde do nanómetro
  (nm). Un nanómetro equivale en escala á billonésima
  parte dun metro (1 nm =1 x 10^9 m).
• Existen nanotubos de moitos materiais, tales como
  silicio ou nitruro de boro, pero xeralmente o termo
  se aplica aos nanotubos de carbono.
• Os nanotubos de carbono son unha forma alotrópica
  do carbono, como o diamante, o grafito ou
  os fullerenos. A súa estrutura pode considerarse
  procedente dunha lámina de grafito enrolada sobre
  si mesma.
• Dependendo do grao de enrolamento e o xeito como
  se conforma a lámina orixinal, o resultado pode levar
  a nanotubos de distinto diámetro e xeometría
  interna:
 Nanotubos monocapa
 Nanotubos multicapa
• É o material máis duro que se coñece, capaz de
  soportar cargas moi pesadas e de resistir
  densidades de corrente eléctrica moi superiores aos
  cables de cobre.
