Oriented Graphene Nanoribbon Yarn and Sheet from Aligned Multi‐Walled Carbon Nanotube Sheets

Abstract

Highly oriented graphene nanoribbons sheets and yarns are produced by chemical unzipping of self-standing multiwalled carbon nanotube (MWNT) sheets. The as-produced yarns - after being chemically and thermally reduced - exhibit a good mechanical, electrical, and electrochemical performance.
