General description
These graphene nanoplatelets can enhance mechanical properties such as stiffness, strength, and surface hardness of the matrix material. They are compatible with nearly all polymers and can serve as an active ingredient in inks or coatings, as well as an excellent additive for various types of plastics. The manufacturing processes used are non-oxidizing, resulting in a pristine graphitic surface composed of sp² carbon molecules, making them particularly suitable for applications that require high electrical or thermal conductivity. The particles have an average thickness of approximately 6-8 nanometers and a typical surface area of 120 to 150 m²/g.
Other Notes
Graphene nanoplatelets have naturally occurring functional groups like ethers, carboxyls, or hydroxyls that can react with atmospheric humidity to form acids or other compounds. These functional groups are present on the edges of the particles and their wt% varies with particle size.
Features and Benefits
We are committed to bringing you Greener Alternative Products that adhere to one of the four categories of Greener Alternatives. Graphene Nanoplatelets (GNPs) enhance lithium-ion battery performance by increasing reversible capacity and improving charge rates, while their high specific surface area supports efficient lithium ion transport.
