Ultra Graphene – Powder
OVERVIEW
Since the discovery of graphene, the industry has been lacking methods and manufacturing protocols for the production of high-quality graphene and is effective at preventing the restacking of individual layers of graphene sheets.
Nanotech Energy has made a lot of progress towards that end. Ultra-graphene is a product with single-layer carbon sheets and low oxygen content and can be readily processed for solutions.
