Journal ArticleDOI
Improved Synthesis of Graphene Oxide
Daniela C. Marcano,Dmitry V. Kosynkin,Jacob M. Berlin,Alexander Sinitskii,Zhengzong Sun,Alexander S. Slesarev,Lawrence B. Alemany,Wei Lu,James M. Tour +8 more
TL;DR: An improved method for the preparation of graphene oxide (GO) is described, finding that excluding the NaNO(3), increasing the amount of KMnO(4), and performing the reaction in a 9:1 mixture of H(2)SO(4)/H(3)PO(4) improves the efficiency of the oxidation process.
Journal ArticleDOI
Longitudinal unzipping of carbon nanotubes to form graphene nanoribbons
Dmitry V. Kosynkin,Amanda L. Higginbotham,Alexander Sinitskii,Jay R. Lomeda,Ayrat M. Dimiev,B. Katherine Price,James M. Tour +6 more
TL;DR: A simple solution-based oxidative process for producing a nearly 100% yield of nanoribbon structures by lengthwise cutting and unravelling of multiwalled carbon nanotube (MWCNT) side walls is described.
Journal ArticleDOI
Functionalization of carbon nanotubes by electrochemical reduction of aryl diazonium salts: a bucky paper electrode
Jeffrey L. Bahr,Jiping Yang,Dmitry V. Kosynkin,Michael J. Bronikowski,Richard E. Smalley,James M. Tour +5 more
TL;DR: Nanotubes derivatized with a 4-tert-butylbenzene moiety were found to possess significantly improved solubility in organic solvents and represents the marriage of wire-like nanotubes with molecular electronic devices.
Journal ArticleDOI
Diazonium Functionalization of Surfactant-Wrapped Chemically Converted Graphene Sheets
TL;DR: Surfactant-wrapped chemically converted graphene sheets obtained from reduction of graphene oxide with hydrazine were functionalized by treatment with aryl diazonium salts, allowing alternative avenues for simple incorporation into different polymer matrices.
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.
