Journal ArticleDOI
Effect of friction on oxidative graphite intercalation and high-quality graphene formation
Steffen Seiler,Christian E. Halbig,Christian E. Halbig,Fabian Grote,Fabian Grote,Philipp Rietsch,Philipp Rietsch,Felix Börrnert,Ute Kaiser,Bernd Meyer,Siegfried Eigler,Siegfried Eigler +11 more
TL;DR: It is shown that reducing molecular friction by using highly crystalline graphite and mild oxidizing conditions is the key to high quality graphene.
Journal ArticleDOI
Chemistry with graphene and graphene oxide-challenges for synthetic chemists.
Siegfried Eigler,Andreas Hirsch +1 more
TL;DR: In this article, a review of the state-of-the-art for the chemical functionalization of graphite, graphene, graphite oxide, and graphite-based nanomaterials is presented.
Journal ArticleDOI
Chemistry with Graphene and Graphene Oxide - Challenges for Synthetic Chemists
Siegfried Eigler,Andreas Hirsch +1 more
TL;DR: The structure of graphene and graphene oxide is described and the most important synthetic methods used for the production of these carbon-based nanomaterials are outlined and the state-of-the-art for their chemical functionalization by noncovalent and covalent approaches are summarized.
Journal ArticleDOI
Visualization of defect densities in reduced graphene oxide
TL;DR: In this paper, an efficient reducible graphene oxide (GO) was obtained, even if a high degree of functionalization is present Graphite with few defects was used as starting material and oxidized according to Hummer's method.
Journal ArticleDOI
Wet Chemical Synthesis of Graphene
Siegfried Eigler,Michael Enzelberger-Heim,Stefan Grimm,Philipp Hofmann,Wolfgang Kroener,Andreas Geworski,Christoph Dotzer,Michael Röckert,Jie Xiao,Christian Papp,Ole Lytken,Hans-Peter Steinrück,Paul Müller,Andreas Hirsch +13 more
TL;DR: The protocol allows the wet chemical synthesis of graphene from a new form of graphene oxide that consists of an intact hexagonal σ-framework of C-atoms that can be easily reduced to graphene that is no longer dominated by defects.
