Graphene sheets produced by carbon nanotubes unzipping and their performance as supercapacitor

Carbon nanotubes (CNTs) are well known by their unique properties, such as high electrical conductivity and chemical stability, which can improve charge transfer, facilitating double layer charging in supercapacitor devices. In this work we report on a simple method to unzip CNTs, producing graphene sheets. The amount of hydrogen atoms in the nanotubes synthesis by micro-wave chemical vapor deposition is a critical parameter for unzipping...
