A nanofiber sheet is described that is composed of a substrate and a layer of oriented nanofibers. Nanofibers of the sheet can be oriented in a common direction. In some orientations, light absorbent sheets can absorb over 99.9%, and in some cases over 99.95%, of the intensity of light incident upon the sheet. Methods for fabricating a light absorbent sheet are also described.

This present invention relates to oxidized, discrete carbon nanotubes in dispersions, especially for use in printing inks. The dispersions can include materials such as elastomers, thermosets and thermoplastics or aqueous dispersions of open-ended carbon nanotubes with additives. A further feature of this invention relates to the development of a dispersion of oxidized, discrete carbon nanotubes that are electrically conductive.

The present application pertains to dispersions comprising oxidized, discrete carbon nanotubes and high-surface area carbon nanotubes. The oxidized, discrete carbon nanotubes comprise an interior and exterior surface, each surface comprising an interior surface oxidized species content and an exterior surface oxidized species content. The interior surface oxidized species content differs from the exterior surface oxidized species content by at least 20%, and as high as 100%. The high-surface area nanotubes are generally single-wall nanotubes. The BET surface area of the high-surface area nanotubes is from about 550 m.sup.2/g to about 1500 m.sup.2/g according to ASTM D6556-16. The aspect ratio is at least about 500 up to about 6000. The dispersions comprise from about 0.1 to about 30% by weight nanotubes based on the total weight of the dispersion.
