Claims107
An electrically conductive film comprising:
- a plurality of carbon nanotubes with an outer diameter of less than 3.5 mm wherein said film has a light transmittance of at least 60% and a surface resistance of less than about 1010 ohms/square.
A dispersion of nanotubes comprising a plurality of carbon nanotubes with an outer diameter of less than 3.5 nm, wherein when applied to a surface as a film of carbon nanotubes, said film is electrically conductive and allows for a light transmittance of at least 60% through said film.
An electrically conductive film comprising:
- a plurality of substantially single-walled or double-walled carbon nanotubes wherein said film has a light transmittance of at least 60% and a haze value of 5.7% or less, and said carbon nanotubes provide a surface resistance to said film of 104 ohms/square or less.
An electrically conductive film comprising:
- a plurality of substantially single-walled, carbon nanotubes wherein said film has a light transmittance of at least 60% and said carbon nanotubes provide a volume resistance to said film of 104 ohms-cm or less and said film has a haze value of 5.7% or less.
An electrically conductive film consisting essentially of a film of single-walled carbon nanotubes, wherein said film has a light transmittance of at least 60% and at least some of said single-walled carbon nanotubes are oriented.
