    We report a Langmuir–Blodgett (LB) approach for highly-efficient fabrication of nanoscrolls from functionalized graphene oxide single sheets. Transmission electron microscope study reveals that the scroll has a tubular structure without caps at its ends. The scrolls align parallel to the moving barriers of the LB equipment and exhibit a loose-dense pattern during the LB compression process. We find that specific solvents can unwind the scrolled structures. Electrical characterization of the well-aligned scrolls was also performed. The method demonstrated here opens up a new avenue for high-yield fabrication of carbon nanoscrolls using functionalized graphene oxide as the building blocks.
