Abstract: A fabric of nanofibers that includes an adhesive is described. The nanofibers can be twisted or both twisted and coiled prior to formation into a fabric. The adhesive can be selectively applied to or infiltrated within portions of the nanofibers comprising the nanofiber fabric. The adhesive enables connection of the nanofiber fabric to an underlying substrate, even in cases in which the underlying substrate has a three-dimensional topography, while the selective location of the adhesive on the fabric limits the contact area between the adhesive and the nanofibers of the nanofiber fabric. This limited contact area can help preserve the beneficial properties of the nanofibers (e.g., thermal conductivity, electrical conductivity, infra-red (IR) radiation transparency) that otherwise might be degraded by the presence of adhesive.

Abstract: A triboelectric generator includes a set of two triboelectric elements. A first triboelectric element includes a nanofiber sheet and a coating of a first material having a positive triboelectric affinity. A second triboelectric element includes a nanofiber sheet and a coating of a second material having a negative triboelectric affinity. The first and second triboelectric elements are arranged so that confronting surfaces of the elements can reversibly contact one another. Repeated contact between the two triboelectric elements can transfer electrons and thus generate electrical energy. In some examples, a plurality of sets of first and second triboelectric elements can be arranged to increase surface area of contact between elements, and thus the amount of electrical energy produced per unit time.

Abstract: A dispenser is described for dispensing nanofiber yarns that includes a housing that defines an inlet, an outlet, and a chamber. A spool, around which is wound a length of nanofiber yarn, is disposed within the chamber defined by the housing. The nanofiber yarn is threaded from the chamber through the outlet and can be dispensed in a controlled way that reduces the likelihood of developing knots within the nanofiber yarn, and which facilitates convenient application of the yarn onto an underlying surface. In some cases, the dispenser can be used to concurrently dispense an adhesive or other polymer along with the nanofiber yarn.

Abstract: Techniques are described for transferring nanofiber forests using transfer films that either lack a conventional adhesive at the substrate—nanofiber forest interface or that include a diffusion barrier that prevents diffusion of adhesive molecules (or other polymer molecules mobile at ambient temperatures) into the nanofiber forest. These techniques can be applied to single layer nanofiber forests or stacks of multiple nanofiber forest. By selecting the bond strength between the nanofiber forest and the transfer films, the nanofibers can be aligned in a common direction that includes, but is not limited to, perpendicular to a substrate or transfer film.

Abstract: Systems for fabricating nanofiber yarn at rates of at least 30 m/min (1.8 kilometers (km)/hour (hr)) using a “false twist” nanofiber yarn spinner and a false twist spinning technique are disclosed. In a false twist spinning technique, a twist is introduced to nanofibers in a strand by twisting the nanofibers at points between ends of the strand. This is in contrast to the “true twist” technique where one end of a strand is fixed and the opposing end of the strand is rotated to introduce the twist to intervening portions of yarn.

Abstract: Nanofiber membranes are described that include multiple layers of nanofiber structures, where each structure is a composite composition of multiwall carbon nanotubes and one or both of single wall and/or few walled carbon nanotubes. By selecting the relative proportions of multiwall and one or more of single/few wall carbon nanotubes in a nanofiber film, the membrane can be fabricated to withstand the heating that occurs during operation in an EUV lithography machine, while also having enough mechanical integrity to withstand pressure changes of between 1 atmosphere (atm) and 2 atm between operating cycles of an EUV lithography machine.
