Publication number: 20160273133Abstract: The present invention is directed to nanofiber yarns, ribbons, and sheets; to methods of making said yarns, ribbons, and sheets; and to applications of said yarns, ribbons, and sheets. In some embodiments, the nanotube yarns, ribbons, and sheets comprise carbon nanotubes. Particularly, such carbon nanotube yarns of the present invention provide unique properties and property combinations such as extreme toughness, resistance to failure at knots, high electrical and thermal conductivities, high absorption of energy that occurs reversibly, up to 13% strain-to-failure compared with the few percent strain-to-failure of other fibers with similar toughness, very high resistance to creep, retention of strength even when heated in air at 450° C. for one hour, and very high radiation and UV resistance, even when irradiated in air. Furthermore these nanotube yarns can be spun as one micron diameter yarns and plied at will to make two-fold, four-fold, and higher fold yarns.Type: ApplicationFiled: November 25, 2015Publication date: September 22, 2016Applicant: Board of Regents, The University of Texas SystemInventors: Mei Zhang, Shaoli Fang, Ray H.

Patent number: 9154058Abstract: Nanofiber actuators and strain amplifiers having a material that generates a force or generates a displacement when directly or indirectly electrically driven. This material is an aerogel or a related low density or high density network comprising conducting fibers that are electrically interconnected and can substantially actuate without the required presence of either a liquid or solid electrolyte. Reversible or permanently frozen actuation is used to modify the properties of the actuator material for applications.Type: GrantFiled: August 17, 2009Date of Patent: October 6, 2015Assignee: Board of Regents, The University of Texas SystemInventors: Ray H.
