  Carbon nanoscrolls (CNSs) are nanomaterials with geometry resembling graphene
layers rolled up into a spiral (papyrus-like) form. Effects of hydrogenation
and temperature on the self-scrolling process of two nanoribbons interacting
with a carbon nanotube (CNT) have been studied by molecular dynamics
simulations for three configurations: (1) graphene/graphene/CNT; (2)
graphene/graphane/CNT, and (3) graphane/graphane/CNT. Graphane refers to a
fully hydrogenated graphene nanoribbon. Nanoscroll formation is observed for
configurations (1) and (2) for temperatures 300-1000 K, while nanoribbons wrap
CNT without nanoscroll formation for configuration (3).
