Warning: This post doesn't intend to help.
Over the years, other than carbon fiber, every other commercial product that involves the allotropes of carbon is an empty promise and cash grab. That means graphite, carbon nanotubes...and so on, and graphene is no exception. Carbon nanofiber(CNF), while not an allotrope of carbon, could potentially end up as another empty promise.
Graphite is essentially pencil. The Hybtonite glue by Amroy(gone bust) contained carbon nanotubes that really did more harm than good for Stiga. Carbon nanofiber is just a piece of fancy but expensive af paper.
