Carbon nanotube film, carbon nanotube film precursor, method for manufacturing the same and a light source

摘要

A carbon nanotube film includes a plurality of successively oriented carbon nanotubes joined end-to-end by Van der Waals attractive force therebetween. The carbon nanotubes define a plurality of first areas and a plurality of second areas. The first areas and the second areas have different densities of carbon nanotubes. A method for manufacturing the same is also provided. A light source using the carbon nanotube film is also provided.
