Abstract:Molecular dynamics simulations demonstrate that graphene nanoscrolls (GNSs) can be fabricated by self-assembly of isolated carbon nanotubes (CNTs) with cut line defects. The scrolling process and energy analysis show that van der Waals interactions and π-π stacking are primary causes. The diameter and length of CNTs should meet some required conditions to guarantee the scroll configuration. The dependence of scroll-forming on temperature and edge structure is also investigated. It is remarkable that fissures w… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
