Abstract:
A flexible sheet comprising a composite sheet, the composite sheet comprising a binder and an aggregate containing a plurality of carbon nanotubes that is disposed in the binder, wherein the aggregate is formed as a waveform structure travelling along a single direction in a plane of the composite sheet, is provided. The disclosed flexible sheets may be used as thermally conductive components, electrically conductive components, antistatic components, electromagnetic wave shields, and/or heating elements, in addition to other possible uses.
Abstract:
A nanofiber forest is described that has been processed to increase a number of nanofibers per unit area (referred to as “areal density” or, equivalently, “density”) compared to the nanofiber forest in its as-synthesized state. This increase in areal density is accomplished by physically manipulating a deformable substrate on which the nanofiber forest is disposed. At a high level, this physical manipulation begins by transferring the nanofiber forest from a growth substrate to a deformable substrate. A surface area of the deformable substrate is reduced relative to a surface area of the substrate when the nanofiber forest was attached. This reduction in area causes the nanofibers in the forest to move closer to one another, thus increasing the number of nanofibers per unit area.

Abstract:
A composite including a heat conformable polymer and a nanofiber sheet is disclosed. The heat conformable polymer can be a hot melt adhesive, and the combination can provide an electrically conductive hot melt adhesive composite. The nanofiber layer is protected and the composite is conformable and/or can be adhered to a variety of surfaces.
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:
Methods, systems, and apparatus for fabricating nanofiber yarn at rates at 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. 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:
It is an object of the present invention to provide a carbon nanotube forest laminated body that enables easy production of a carbon nanotube sheet from a carbon nanotube forest and a method of producing a carbon nanotube forest laminated body. The carbon nanotube forest laminated body of the present invention includes a support having an adhesive (sticky) surface and a carbon nanotube forest provided on the surface of the support. The surface of the support has an adhesive strength of 0.01 N/25 mm or more and 2 N/25 mm or less, and the carbon nanotube forest is provided on the surface.
