TL;DR: It is shown that high-shear mixing of graphite in suitable stabilizing liquids results in large-scale exfoliation to give dispersions of graphene nanosheets in liquid volumes from hundreds of millilitres up to hundreds of litres and beyond.
Journal ArticleDOI
Liquid exfoliation of solvent-stabilized few-layer black phosphorus for applications beyond electronics
Damien Hanlon,Claudia Backes,Evie Doherty,Clotilde S. Cucinotta,Nina C. Berner,Conor S. Boland,Kangho Lee,Andrew Harvey,Peter Lynch,Zahra Gholamvand,Saifeng Zhang,Kangpeng Wang,Kangpeng Wang,Glenn Moynihan,Anuj Pokle,Quentin M. Ramasse,Niall McEvoy,Werner J. Blau,Jun Wang,Gonzalo Abellán,Frank Hauke,Andreas Hirsch,Stefano Sanvito,David D. O'Regan,Georg S. Duesberg,Valeria Nicolosi,Jonathan N. Coleman +26 more
TL;DR: It is demonstrated that high-quality, few-layer BP nanosheets, with controllable size and observable photoluminescence, can be produced in large quantities by liquid phase exfoliation under ambient conditions in solvents such as N-cyclohexyl-2-pyrrolidone (CHP).
Journal ArticleDOI
Sensitive, High-Strain, High-Rate Bodily Motion Sensors Based on Graphene–Rubber Composites
Conor S. Boland,Umar Khan,Claudia Backes,Arlene O’Neill,Joe McCauley,Shane Duane,Ravi Shanker,Yang Liu,Izabela Jurewicz,Alan B. Dalton,Jonathan N. Coleman +10 more
TL;DR: A simple method to infuse liquid-exfoliated graphene into natural rubber to create conducting composites is described, which are excellent strain sensors displaying 10(4)-fold increases in resistance and working at strains exceeding 800%.
Journal ArticleDOI
Sensitive electromechanical sensors using viscoelastic graphene-polymer nanocomposites
Conor S. Boland,Umar Khan,Gavin Ryan,Sebastian Barwich,Romina Charifou,Andrew Harvey,Claudia Backes,Zheling Li,Mauro S. Ferreira,Matthias E. Möbius,Robert J. Young,Jonathan N. Coleman +11 more
TL;DR: By considering both the connectivity and mobility of the nanosheets, a quantitative model is developed that completely describes the electromechanical properties of graphene, allowing the manufacture of strain sensors that can detect respiration and the footsteps of spiders.
Journal ArticleDOI
Edge and confinement effects allow in situ measurement of size and thickness of liquid-exfoliated nanosheets
Claudia Backes,Ronan J. Smith,Niall McEvoy,Nina C. Berner,David McCloskey,Hannah C. Nerl,Arlene O’Neill,Paul J. King,Thomas M. Higgins,Damien Hanlon,Nils Scheuschner,Janina Maultzsch,Lothar Houben,Georg S. Duesberg,John F. Donegan,Valeria Nicolosi,Jonathan N. Coleman +16 more
TL;DR: The resultant controllability of concentration, size and thickness facilitates the preparation of dispersions with pre-determined properties such as high monolayer-content, leading to first measurement of A-exciton MoS2 luminescence in liquid suspensions.
