Journal ArticleDOI
Solutions of negatively charged graphene sheets and ribbons.
Cristina Vallés,Carlos Drummond,Hassan Saadaoui,Clascídia A. Furtado,Maoshuai He,Olivier Roubeau,Luca Ortolani,Marc Monthioux,Alain Pénicaud +8 more
TL;DR: Negatively charged graphene layers from a graphite intercalation compound spontaneously dissolve in N-methylpyrrolidone, yielding stable, air-sensitive, solutions of laterally extended atom-thick graphene sheets and ribbons with dimensions over tens of micrometers.
Journal ArticleDOI
Electrical percolation in graphene-polymer composites
Alexander J. Marsden,Dimitrios G. Papageorgiou,Cristina Vallés,Andrea Liscio,Vincenzo Palermo,Mark A. Bissett,Robert J. Young,Ian A. Kinloch +7 more
TL;DR: In this paper, the progress in graphene-polymer composites for electrical applications is discussed and the current optimal composites are presented, and the example of strain sensors is used to demonstrate their application.
Journal ArticleDOI
Flexible conductive graphene paper obtained by direct and gentle annealing of graphene oxide paper
TL;DR: In this paper, the authors report the fabrication of flexible conductive graphene paper through a direct and gentle annealing process of graphene oxide paper, which leads to a significant removal of disruptive oxygen-containing functional groups, and to a considerable recovery of the sp2 network structure.
Journal ArticleDOI
The Mechanics of Reinforcement of Polymers by Graphene Nanoplatelets
Robert J. Young,Mufeng Liu,Ian A. Kinloch,Suhao Li,Xin Zhao,Cristina Vallés,Dimitrios G. Papageorgiou +6 more
TL;DR: In this paper, a detailed study has been undertaken of the mechanisms of stress transfer in polymeric matrices with different values of Young's modulus, Em, reinforced by graphene nanoplatelets (GNPs).
Journal ArticleDOI
Deoxygenation of Graphene Oxide: Reduction or Cleaning?
Helen R. Thomas,Stephen Day,William E. Woodruff,Cristina Vallés,Robert J. Young,Ian A. Kinloch,Gavin W. Morley,John V. Hanna,Neil R. Wilson,Jonathan P. Rourke +9 more
TL;DR: In this paper, the authors show that the two-component model of graphene oxide (GO), composed of highly oxidized carbonaceous debris complexed to oxygen functionalized graphene sheets, is a generic feature of the synthesis of GO, independent of oxidant or protocol used.
