Abstract: Techniques are described for controlling widths of nanofiber sheets drawn from a nanofiber forest. Nanofiber sheet width can be controlled by dividing or sectioning the nanofiber sheet in its as-drawn state into sub-sheets as the sheet is being drawn. A width of a sub-sheet can be controlled or selected so as to contain regions of uniform nanofiber density within a sub-sheet (thereby improving nanofiber yarn consistency) or to isolate an inhomogeneity (whether a discontinuity is the sheet (e.g., a tear) or a variation in density) within a sub-sheet. Techniques for dividing a nanofiber sheet into sub-sheets includes mechanical, corona, and electrical arc techniques.

Abstract: Examples described include composite nanofibers sheets that have been “infiltrated” with a polymer (i.e., the polymer has flowed past a surface of the nanofiber sheet and into at least some of spaces within the sheet defined by the nanofibers). An adhesive nanofiber tape is formed when the infiltrating polymer is an adhesive and the adhesive infiltrates the nanofiber sheet from a one major surface of the nanofiber sheet. In other described examples, some portions of nanofibers in the sheet have been conformally coated with at least one metal layer.

Abstract: A nanofiber sheet dispenser that houses a nanofiber forest from which a nanofiber sheet can be drawn is described. Using the nanofiber sheet dispenser, a nanofiber forest disposed on a substrate can be moved, transported, and/or shipped with a reduced risk of damage relative to transporting a nanofiber sheet. Techniques are also described for configuring the nanofiber sheet dispenser so that a nanofiber sheet can be conveniently drawn from the forest and, in some cases, drawn so as to form a nanofiber yarn that is continuous with both the nanofiber sheet and the nanofiber forest, the latter of which is within the nanofiber sheet dispenser.

Abstract: Nerve scaffolds are described that include a tubular outer housing fabricated from a biocompatible polymer, within which are disposed a plurality of carbon nanofiber yarns. The carbon nanofiber yarns, which can be separated by distances roughly corresponding to an average nerve fiber diameter, provide surfaces on which nerve fibers can regrow. Because the proximate carbon nanofiber yarns can support individual nerve fibers, a nerve can be regenerated with a reduced likelihood of undesirable outcomes, such as nerve pain or reduced nerve function.

Abstract: An insulated nanofiber having a continuous nanofiber collection extending along a longitudinal axis with an outside surface and an inside portion is described. A first material infiltrates the inside portion, where the outside surface of the nanofiber collection is substantially free of the first material. An electrically-insulating second material coats the outside surface of the nanofiber collection. A method of making an insulated nanofiber collection is also disclosed.

Abstract: A density of a nanofiber sheet can be changed using an edged surface, and in particular an arcuate edged surface. As described herein, a nanofiber sheet is drawn over (and in contact with) an arcuate edged surface. Depending on whether the arcuate surface facing a direction opposite the direction in which the nanofiber sheet is being drawn is convex or concave determines whether the nanofiber sheet density is increased relative to the as-drawn sheet or decreased relative to the as-drawn sheet.

Abstract: Techniques are disclosed for producing multilayered composites of adhesive nanofiber composites. Specifically, one or more sheets of highly aligned nanofibers are partially embedded in an adhesive such that at least a portion of the nanofiber sheet is free from adhesive and is available to conduct current with adjacent electrical features. In some example embodiments, the adhesive nanofiber composites are metallized with a conductive metal and in these and other embodiments, the adhesive nanofiber composites may also be stretchable.
