Abstract
Official abstract text for this publication.
An array of discrete nanofiber films that are physically separated from one another are described. Techniques for forming the nanofiber film array are also described. Techniques for forming these structures include placing a suspension of nanofibers and/or nanoparticles on a patterned substrate. A pressure differential is applied, drawing the solvent of the suspension through holes in a mask. The nanofibers collect on an impermeable layer on the mask in a pattern corresponding to the negative features (grooves, holes, trenches) of the mask as the solvent is flowed through the holes.
First claim
Opening claim text (preview).
What is claimed is: 1. A nanofiber assembly comprising: a nanofiber film has a first planar surface and a second planar surface at an opposing side of the first planar surface, the first planar surface being free from a supporting substrate, and at least one first nanofiber film disk on the second planar surface of the nanofiber film, wherein the at least one first nanofiber film disk comprises a plurality of nanofibers arranged in a planar orientation and randomly oriented relative to each other, has at least one geometry shape, and forms a pattern on the nanofiber film, and wherein the nanofiber film comprises a drawn nanofiber sheet, a filtered nanofiber film, or a combination thereof. 2. The nanofiber assembly of claim 1 , further comprising a second nanofiber film disk, wherein the at least one first nanofiber film disk and the second nanofiber film disk are discrete and separated from one another. 3. The nanofiber assembly of claim 2 , wherein the at least one first nanofiber film disk and the second nanofiber film disk form at least one array. 4. The nanofiber assembly of claim 1 , wherein nanofibers included in the at least one first nanofiber film disk are different from nanofibers included in the nanofiber film. 5. The nanofiber assembly of claim 1 , wherein the at least one first nanofiber film disk has at least one enclosed void geometry shape. 6. The nanofiber assembly of claim 1 , wherein the nanofiber assembly is extreme ultraviolet (EUV) radiation-transparent. 7. The nanofiber assembly of claim 6 , wherein the EUV radiation has a wavelength between 10 nm to 124 nm.
