Graphene Nanoribbons & Graphene Nanoplatelets

NTherma’s family of graphene nanomaterials compose of graphene nanoribbons and graphene nanoplatelets. Our patent-pending technology produces these graphene nanomaterials with greater than 99% purity, high crystallinity and at significantly lower cost. One of the unique features of the graphene nanoribbons is length uniformity and customizable up to 200 μm. Our production process yields high and stable quality for both types of graphene nanomaterials.

Graphene nanoribbons with high uniformity and controlled lengths can offer uniform electrical, optical, and mechanical properties for many applications. For example, longer length graphene nanoribbons will enable continuous electrical property at low loading composition. NTherma’s patent-pending production method for both graphene nanomaterials also has the advantages in integration for achieving high yield and consistent manufacturing. High performances and higher consistent quality of products are achievable for the following applications:

  • Transparent conductive film with high transparency and low surface resistance
  • Electrode materials for battery with high charging rates and high consistency
  • Flexible electronics connections using graphene nanoribbons
  • Oil and lubricant additives with high solubility and stable shelf life
  • Coating and Paint additives with low loading for higher hardness and antioxidant properties
