Strong, Light, Multifunctional Fibers of Carbon Nanotubes with Ultrahigh Conductivity
Natnael Behabtu,Colin C. Young,Dmitri E. Tsentalovich,Olga Kleinerman,Xuan Wang,Anson W. K. Ma,E. Amram Bengio,E. Amram Bengio,Ron F. ter Waarbeek,De Jong Jorrit,Ron E. Hoogerwerf,Steven B.

TL;DR: High-performance multifunctional carbon nanotube (CNT) fibers that combine the specific strength, stiffness, and thermal conductivity of carbon fibers with the specific electrical Conductivity of metals are reported.
Journal ArticleDOI
Spontaneous high-concentration dispersions and liquid crystals of graphene
Natnael Behabtu,Jay R. Lomeda,Micah J. Green,Amanda L. Higginbotham,Alexander Sinitskii,Dmitry V. Kosynkin,Dmitri E. Tsentalovich,A. Nicholas G. Parra-Vasquez,Judith Schmidt,Ellina Kesselman,Yachin Cohen,Yeshayahu Talmon,James M. Tour,James M. Tour,Matteo Pasquali +14 more
TL;DR: It is shown that graphite spontaneously exfoliates into single-layer graphene in chlorosulphonic acid, and dissolves at isotropic concentrations as high as approximately 2 mg ml(-1), which is an order of magnitude higher than previously reported values.
Journal ArticleDOI
True solutions of single-walled carbon nanotubes for assembly into macroscopic materials
Virginia A. Davis,A. Nicholas G. Parra-Vasquez,Micah J. Green,Micah J. Green,Pradeep K. Rai,Natnael Behabtu,Valentin Prieto,Richard Booker,Judith Schmidt,Ellina Kesselman,Wei Zhou,Hua Fan,W. Wade Adams,Robert H. Hauge,John E. Fischer,Yachin Cohen,Yeshayahu Talmon,Richard E. Smalley,Matteo Pasquali +18 more
TL;DR: It is shown that single-walled nanotubes form true thermodynamic solutions in superacids, and the full phase diagram is reported, allowing the rational design of fluid-phase assembly processes for bottom-up assembly of nanot tubes and nanorods into functional materials.
Journal ArticleDOI
High-Performance Carbon Nanotube Transparent Conductive Films by Scalable Dip Coating
Francesca Mirri,Anson W. K. Ma,Tienyi T. Hsu,Natnael Behabtu,Shannon L. Eichmann,Colin C. Young,Dmitri E. Tsentalovich,Matteo Pasquali +7 more
TL;DR: Transparent conductive carbon nanotube films were fabricated by dip-coating solutions of pristine CNTs dissolved in chlorosulfonic acid and then removing the CSA to preserve the length and quality and operate at high CNT concentration and coating speed without using surfactants.
Journal ArticleDOI
Carbon nanotube-based neat fibers
TL;DR: These techniques may be divided into ‘liquid’ methods, where CNTs are dispersed into a liquid and solutionspun into fibers, and ‘solid” methods,where CNTS are directly spun into ropes or yarns, which yield fibers whose properties are not sufficiently close to optimal.
