Unzipping of Single-walled carbon nanotubes for producing Graphene Nano-ribbon
Graphene is a one-atom-thick allotrope of carbon. It is a 2-dimensional nanomaterial. The structure is similar to honeycomb with sp2 hybridized carbon atoms. It possesses noticeable mechanical, electrical, and optical properties[1]. The production method of graphene involves chemical vapour deposition on copper/nickel metal sheet or via chemical/ mechanical exfoliation processes. The mechanical exfoliation process is one of the best technique for achieving defect-free graphene[2]. Graphene nanoribbons (GNR) are 1-dimensional graphene structures whose properties are defined by the width and the thickness of the GNR. This GNR is produced by lithography, chemical technique, and by unzipping nanotubes[3]. Among which unzipping provides…
