Graphene NMP Dispersion, Purity: 99.5%, Graphene: 2,0 wt%

Graphene NMP Dispersion, Purity: 99.5%, Graphene: 2.0 wt% refers to a suspension of high-purity graphene in N-Methyl-2-pyrrolidone (NMP) as the solvent, with graphene making up 2.0 weight percent of the total mixture.

Properties of Graphene NMP Dispersion:

1. Stability:
   • The NMP solvent ensures the graphene particles remain evenly distributed and prevents aggregation or settling over time.
2. High Graphene Loading:
   • A 2.0 wt% concentration enables efficient deposition of graphene and provides robust performance in applications requiring higher material content.
3. Electrical and Thermal Conductivity:
   • The graphene retains its excellent electrical and thermal properties, suitable for advanced applications like conductive coatings and heat management.
4. Compatibility:
   • NMP is compatible with various substrates and processes, including solution-based fabrication, printing, and coating.
5. Ease of Use:
   • As a liquid, the dispersion simplifies handling, application, and integration into manufacturing or research workflows.
