Abstract: Nanofiber sheet assemblies include at least one nanofiber sheet and at least one nanofiber grid or web that is used to improve the physical durability of the nanofiber sheet within the assembly. Nanofiber sheet assemblies retain the permeability of the nanofiber sheets to gaseous phase substances. This enables technological applications of nanofiber sheet assemblies to include filters for micron or nano-scale particles that are disposed in gas phase substances.

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: Techniques are described for infiltrating a nanofiber yarn with an infiltration material and removing a surface layer of the infiltration material on at least a portion of the infiltrated nanofiber yarn. This enables an infiltration method by which the infiltration material is selectively disposed within an interior of a nanofiber yarn and not disposed on an exterior surface of at least a portion of a nanofiber yarn. Electrical connection can be established by mechanically connecting an electrode (e.g., a conductive clamp or fitting) directly to the exposed surface of the nanofiber yarn.

Abstract: Methods and systems are described for continuously densifying at least one nanofiber sheet using heat and an applied force that can include both compressive and tensile components. Nanofiber sheets densified using these techniques have a more uniform and more highly aligned microstructure than nanofiber sheets densified using a solvent alone. As a result, the nanofiber sheets of the present disclosure have, for example, higher tensile strength and better electrical conductivity than nanofiber sheets densified using other techniques.

Abstract: A triboelectric generator include at least two yarns, one of which has been infiltrated with a material having a positive triboelectric affinity and one of which has been infiltrated with a material having a negative triboelectric affinity. The at least two yarns are threaded through holes within a disk so that both of the yarns are disposed on both sides of the disk and pass through the holes within the disk. The at least two yarns are helically wrapped (or “coiled”) together on both sides of the disk. During uncoiling, the moving contact between the two yarns, infiltrated with materials having opposite triboelectric affinities, causes an electrical charge to develop. The generated electrical charge can be conducted away for use as electricity.

Abstract: A nanofiber structure is described that is composed of a substrate and a layer of oriented nanofibers. Nanofibers of the layer can be oriented in a common direction. An angle of the common direction can be selected so that nanofibers of the sheet are oriented at an angle with respect to an underlying substrate even if the underlying substrate is not planar. The angle can be used to adapt the sheets to demands as a thermal interface material.

Abstract: 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.

Abstract: A filtration formed nanostructure pellicle film with an ultra-thin zirconium coating is disclosed. The filtration formed nanostructure pellicle film includes a plurality of nanotubes that are intersected randomly to form an interconnected network structure in a planar orientation with enhanced properties, and a zirconium-coated layer. The coated interconnected structure with the zirconium-coated layer allows for a high minimum EUV transmission rate of at least 88%. The interconnected network structure has a thickness ranging from a lower limit of 3 nm to an upper limit of 100 nm, to allow for effective EUV lithography processing.

Abstract: Polymer and nanotube-based actuators that include a thermochromic coating is disclosed. The actuators include a thermochromic material applied to a surface of the core fiber or the conductive element. Upon heating the actuator, the thermochromic coating undergoes a color transition to indicate a pre-determined temperature correlated to a rated critical temperature, important temperature of the actuator components, or a level of actuation.
