Abstract:
1. A method for forming a carbon nanotube (CNT) structure comprising: providing a CNT colloidal solution including carbon nanotubes (CNTs); providing a sacrificial element; immersing the sacrificial element into the CNT colloidal solution to form a CNT structure on the sacrificial element; withdrawing the sacrificial element from the CNT colloidal solution, wherein the sacrificial element is substantially vertically withdrawn relative to the CNT colloidal solution at a speed ranging from about 0.3 mm/min to about 3 mm/min; and separating the CNT structure from the sacrificial element, wherein after separation, the formed CNT structure remains, and wherein separating the CNT structure comprises destroying at least part of a surface of the sacrificial element contacting the CNT structure.
