Samsung patents carbon nanotube film for electronics
Samsung describes a method for creating a thin film made of carbon nanotubes, which are tiny carbon tubes that conduct electricity. The process uses a special chemical linker to bond the nanotubes together on a surface, creating a uniform layer.
In the filing’s own words
A method of preparing a carbon nanotube monolayer film includes applying a bifunctional hydrogen-bond linker onto a substrate to prepare a surface-treated substrate, mixing carbon nanotubes having a heteroatom-containing aromatic polymer coating film with a hydrophobic solvent to obtain a composition and contacting the surface-treated substrate with the composition, and heat-treating the surface-treated substrate contacting the composition.
What exactly they claim (claim 1)
1. A carbon nanotube monolayer film, comprising: a plurality of carbon nanotube composites; and a plurality of bifunctional hydrogen-bond linkers, wherein each of the carbon nanotube composites includes carbon nanotubes and a heteroatom-containing aromatic polymer coating film on surfaces thereof, wherein the plurality of carbon nanotube composites are bonded to each other through hydrogen bonds by the bifunctional hydrogen-bond linkers, and wherein a density of the carbon nanotubes in the carbon nanotube monolayer film is about 60 ea/mm to about 350 ea/mm.
