  • Title: Bending properties of single functionalized graphene sheets probed by atomic force microscopy.
    Author: Schniepp HC, Kudin KN, Li JL, Prud'homme RK, Car R, Saville DA, Aksay IA.
    Journal: ACS Nano; 2008 Dec 23; 2(12):2577-84. PubMed ID: 19206294.
    Abstract:
    We probe the bending characteristics of functionalized graphene sheets with the tip of an atomic force microscope. Individual sheets are transformed from a flat into a folded configuration. Sheets can be reversibly folded and unfolded multiple times, and the folding always occurs at the same location. This observation suggests that the folding and bending behavior of the sheets is dominated by pre-existing kink (or even fault) lines consisting of defects and/or functional groups.
