Abstract
A method includes the following steps. An original carbon nanotube film is provided. The original carbon nanotube film includes a plurality of carbon nanotubes substantially oriented along a first direction. The original carbon nanotube film is suspended. The suspended original carbon nanotube film is soaked with an atomized organic solvent to shrink into a carbon nanotube film. Wherein the atomized organic solvent comprises a plurality of dispersed organic droplets with diameters of larger than or equal to 10 micrometers, and less than or equal to 100 micrometers.
Claims18
A method comprising:
- providing a carbon nanotube array;
- drawing an original carbon nanotube film from the carbon nanotube array, wherein the original carbon nanotube film comprises a plurality of carbon nanotube segments;
- and
- soaking the plurality of carbon nanotube segments in the original carbon nanotube film with an atomized organic solvent at least two times to form a plurality of shrunk carbon nanotube segments, and the plurality of shrunk carbon nanotube segments are intercrossed into a carbon nanotube film with a network structure;
- wherein the atomized organic solvent comprises a plurality of organic droplets with diameters of larger than 20 micrometers, and less than or equal to 100 micrometers.
A method comprising:
- providing a carbon nanotube array;
- drawing an original carbon nanotube film from the carbon nanotube array along a first direction, a first end of the original carbon nanotube film connected to the carbon nanotube array, and a second end of the original carbon nanotube film connected to a collector, thereby forming a suspended original carbon nanotube film;
- applying at least one spray nozzle above the suspended original carbon nanotube film;
- atomizing an organic solvent into a plurality of organic droplets, and spraying the plurality of organic droplets by the at least one spray nozzle on the suspended original carbon nanotube film at least two times to soak the suspended original carbon nanotube film such that a carbon nanotube film is formed, and the carbon nanotube film is a network structure;
- and
- rotating the collector such that the carbon nanotube film makes the original carbon nanotube film moving away form the carbon nanotube array and passing below the at least one spray nozzle to be soaked by the plurality of organic droplets in order,
- wherein diameters of the plurality of organic droplets are larger than 20 micrometers, and less than or equal to 100 micrometers.
A method comprising:
- drawing an original carbon nanotube film from a carbon nanotube array, wherein the original carbon nanotube film comprises a plurality of carbon nanotubes substantially oriented along a same direction;
- and
- soaking the original carbon nanotube film with an atomized organic solvent at least two times, wherein the atomized organic solvent comprises a plurality of organic droplets with diameters of larger than 20 micrometers, and less than or equal to 100 micrometers.
