The structure of carbon nanoscrolls is similar to that of a multi-walled carbon nanotube, but with a spiral-like rolled-up geometry and open edges at the ends.
A number of methods have been reported to produce carbon nanoscrolls, including arc discharge, high-energy ball milling, and intercalation, among others. The wedge based mechanical exfoliation is also reported the similar CNS experimentally.
