    摘要: A method of making a transparent conductive film includes providing a carbon nanotube array and a substrate. At least one carbon nanotube film is extracted from the carbon nanotube array, and stacked on the substrate to form a carbon nanotube film structure. The carbon nanotube film structure is irradiated by a laser beam along a predetermined path to obtain a predetermined pattern. The predetermined pattern is separated from the other portions of the carbon nanotube film, thereby forming the transparent conductive film from the predetermined pattern of the carbon nanotube film.

    摘要: An elastic device includes a first elastic supporter; a second elastic supporter and a carbon nanotube film. The second elastic supporter is spaced from the first elastic supporter. The carbon nanotube film has a first side fixed on the first elastic supporter and a second side opposite to the first side and fixed on the second elastic supporter. The carbon nanotube film includes a plurality of first carbon nanotubes orientated primarily along a first direction and a plurality of second carbon nanotubes having orientations different from the first direction. At least one portion of each of the second carbon nanotubes contacts with at least two adjacent first carbon nanotubes. The carbon nanotube film is capable of elastic deformation along a second direction that is substantially perpendicular to the first direction.
