Abstract
Official abstract text for this publication.
The present invention provides: a film that comprises single-layer carbon nanotubes having shapes which enable the characteristics thereof to be sufficiently exhibited; and a process for producing the film. The film, which comprises single-layer carbon nanotubes, has portions where single-layer carbon nanotubes are densely present and portions where single-layer carbon nanotubes are sparsely present, the dense portions forming a pseudo-honeycomb structure in a surface of the film.
First claim
Opening claim text (preview).
What is claimed is: 1 . A film comprising single-walled carbon nanotubes, wherein the film has a dense portion where the single-walled nanotubes are densely present and a sparse portion where the single-walled nanotubes are sparsely present, and the dense portion forms a pseudo-honeycomb structure on the film. 2 . The film according to claim 1 , wherein the film consists essentially of single-walled carbon nanotubes. 3 . The film according to claim 1 , wherein an average diameter of each of the single-walled carbon nanotubes ranges from 0.7 to 3 nm. 4 . The film according to claim 1 , wherein the dense portion has the single-walled carbon nanotubes, an axis direction of each of which is aligned vertically to the film, and a length of each of the vertically aligned single-walled carbon nanotubes ranges from 1 to 100 μm. 5 . The film according to claim 1 , wherein the sparse portion consists essentially of the single-walled carbon nanotubes, an axis direction of each of which is disposed horizontally to the film. 6 . The film according to claim 1 , wherein an average length of one side of each hexagon of the pseudo-honeycomb structure ranges from 1 to 100 μm. 7 . A material comprising the film according to claim 1 . 8 . A solar cell comprising the film according to claim 1 .
