Patent number: 11913142Abstract: 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.Type: GrantFiled: December 18, 2020Date of Patent: February 27, 2024Assignee: LINTEC OF AMERICA, INC.Inventors: BaeKyun Kim, Julia Bykova, Luis Plata, Yang Yang, Márcio D.

Publication number: 20240034629Abstract: 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.Type: ApplicationFiled: October 10, 2023Publication date: February 1, 2024Applicant: LINTEC OF AMERICA, INC.Inventor: Marcio D.

Patent number: 11549205Abstract: 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.Type: GrantFiled: July 10, 2020Date of Patent: January 10, 2023Assignee: LINTEC OF AMERICA, INC.Inventor: Marcio D.

Patent number: 11524862Abstract: 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.Type: GrantFiled: October 30, 2020Date of Patent: December 13, 2022Assignee: LINTEC OF AMERICA, INC.Inventors: Márcio D.

Publication number: 20220250009Abstract: 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.Type: ApplicationFiled: April 22, 2022Publication date: August 11, 2022Applicant: LINTEC OF AMERICA, INC.Inventor: Marcio D.

Patent number: 11377537Abstract: 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.Type: GrantFiled: March 9, 2018Date of Patent: July 5, 2022Assignee: LINTEC OF AMERICA, INC.Inventors: Marcio D.

Patent number: 11370191Abstract: 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.Type: GrantFiled: July 25, 2018Date of Patent: June 28, 2022Assignee: LINTEC OF AMERICA, INC.Inventors: Marcio D.

Patent number: 11161743Abstract: Placement of nanofibers and yarns comprised of nanofibers onto a substrate are described. The nanofiber yarns are difficult to manipulate with precision given that the diameters can be as little as 5 microns or even less than one micron. As described herein, a placement system is described that can place nanofiber yarns on a substrate at pitches less than 100 ?m, less than 50 ?m, less than 10 ?m, and in some embodiments as low as 2 ?m. In part, this precise placement at small pitches is facilitated by the use of coarse and fine adjustment translators, and a guide connected to a compliant flange. The compliant flange and the guide facilitate consistency of location of a nanofiber yarn.Type: GrantFiled: April 22, 2019Date of Patent: November 2, 2021Assignee: LINTEC OF AMERICA, INC.Inventors: Julia Bykova, Marcio D.
