Patent number: 11884544Abstract: Disclosed here is a method of fabricating a covalently reinforced carbon nanotube (CNT) assembly. The method includes producing a CNT assembly by pulling entangled CNTs from a CNT array fabricated on a substrate, the CNT assembly including a plurality of CNTs that are aligned; and creating covalent bonding between the CNTs of the CNT assembly by applying a high energy ion irradiation to the CNT assembly.Type: GrantFiled: June 20, 2022Date of Patent: January 30, 2024Assignee: Lawrence Livermore National Security, LLCInventors: Xavier N. Lepro Chavez, Chantel M. Aracne-Ruddle, Leonardus Bimo Bayu Aji, Sergei O. Kucheyev, Michael Stadermann

Publication number: 20220403523Abstract: Provided herein is a nanoscale material assembly made up of a plurality of nanoscale structures with a crosslinked polymer thermally deposited on the structures. Also disclosed are methods for preparing the nanoscale material assembly with a deposited crosslinked polymer. Further disclosed are various conditions and materials that when used in the preparation of the nanoscale material assemblies further enhance their mechanical properties. In some embodiments, the nanoscale material assemblies can be either nanoscale yarn assemblies or nanoscale sheet assemblies.Type: ApplicationFiled: July 1, 2022Publication date: December 22, 2022Inventors: Xavier N.
