Abstract
The present application relates to a method of increasing density of aligned carbon nanotubes. Firstly, aligned carbon nanotubes grown on a substrate is transferred to a stretched retractable film. The retractable film is then shrunk along a direction which is perpendicular to the alignment direction of the carbon nanotubes to obtain high density carbon nanotubes. The array of aligned carbon nanotubes is finally transferred from the retractable film to a target substrate. The disclosed method can efficiently obtain high-density high-quality aligned carbon nanotubes at low cost.
