Michael J. McAllister,Je-Luen Li,Douglas H. Adamson,Hannes C. Schniepp,Ahmed Abdala,Jun-Jun Liu,Margarita Herrera-Alonso,David L. Milius,Roberto Car,Robert K. Prud'homme,Ilhan A. Aksay +10 more
TL;DR: In this article, a detailed analysis of the thermal expansion mechanism of graphite oxide to produce functionalized graphene sheets is provided, where it is shown that the decomposition rate of the epoxy and hydroxyl sites exceeds the diffusion rate of evolved gases, yielding pressures that exceed the van der Waals forces holding the graphene sheets together.
Journal ArticleDOI
Functionalized graphene sheets for polymer nanocomposites
T. Ramanathan,Ahmed Abdala,Ahmed Abdala,Sasha Stankovich,Dmitriy A. Dikin,Margarita Herrera-Alonso,Richard D. Piner,Richard D. Piner,Douglas H. Adamson,Hannes C. Schniepp,Xinqi Chen,Rodney S. Ruoff,Rodney S. Ruoff,SonBinh T. Nguyen,Ilhan A. Aksay,Robert K. Prud'homme,L. C. Brinson +16 more
TL;DR: Modulus, ultimate strength and thermal stability follow a similar trend, with values for functionalized graphene sheet- poly(methyl methacrylate) rivaling those for single-walled carbon nanotube-poly(methyl methamphetamine) composites.
Journal ArticleDOI
Graphene/Polymer Nanocomposites
TL;DR: Graphene has emerged as a subject of enormous scientific interest due to its exceptional electron transport, mechanical properties, and high surface area, and when incorporated appropriately, these atomically thin carbon sheets can significantly improve physical properties of host polymers at extremely small loading.
Journal ArticleDOI
Recent advances in graphene based gas sensors
Seba Sara Varghese,Seba Sara Varghese,Sunil P. Lonkar,K.K. Singh,Sundaram Swaminathan,Ahmed Abdala +5 more
TL;DR: Graphene, a single, one-atom-thick sheet of carbon atoms arranged in a honeycomb lattice and the two-dimensional building block for carbon materials, has attracted great interest for a wide range of applications as discussed by the authors.
Journal ArticleDOI
Graphene/polyethylene nanocomposites: Effect of polyethylene functionalization and blending methods
Hyunwoo Kim,Shingo Kobayashi,Mohd A. AbdurRahim,Minglun J. Zhang,Albina Khusainova,Marc A. Hillmyer,Ahmed Abdala,Christopher W. Macosko +7 more
TL;DR: In this article, a thermally reduced graphene oxide (TRG) was blended via melt and solvent blending with linear low density polyethylene (LLDPE) and its functionalized analogs (amine, nitrile and isocyanate) produced using a ring-opening metathesis polymerization (ROMP) strategy.
