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.

Differentiating Factor (What makes it unique)

 

ULTRA Graphene produced by our proprietary top-down process exhibits an excellent combination of low oxygen content, high conductivity, and high accessible surface area, making it the closest mass-produced alternative to CVD graphene. During processing, the truly single layer nature of ULTRA Graphene is still preserved, resulting in an ultra-low apparent density.

 

Potential Markets

 

With all the features combined, Ultra Graphene will find its role in a wide variety of industries:

  • consumer electronics,
  • military and defenses,
  • auto industry,
  • research and development labs, etc.
