The formation of carbon nanotubes into forests, yarns and films is reviewed. In forests formed on a substrate with a catalyst metal layer, carbon nanotubes are oriented with their tube axis perpendicular to the substrate. Carbon nanotube yarns are prepared either by spinning a suspension of them under different circumstances, in-situ spinning during their preparation or by direct spinning from their forest. Carbon nanotube films are prepared either by filtering their suspension, in-situ formation or direct drawing.
