Graphene Water Dispersion, Purity: 99.5%, Black Liquid, Graphene: 2 wt%
Graphene Water Dispersion, Purity: 99.5%, Black Liquid, Graphene: 2 wt% refers to a stable suspension of graphene particles in water, where the graphene concentration is 2 weight percent (wt%) and the purity of the graphene is 99.5%.
Properties of Graphene Water Dispersion:
- Stability:
- The dispersion is formulated to ensure the graphene particles are uniformly distributed and do not settle or aggregate over time.
- Ease of Use:
- Being water-based, the dispersion can be easily diluted, applied, or integrated into various processes without requiring harmful organic solvents.
- Electrical Conductivity:
- The graphene retains its high electrical conductivity, making it suitable for applications in electronics and conductive coatings.
- Thermal Conductivity:
- Graphene’s excellent thermal properties are preserved, enabling its use in heat dissipation and thermal management.
- High Loading:
- A 2 wt% concentration provides more graphene per unit volume compared to lower-concentration dispersions, making it efficient for applications needing higher graphene content.
Applications of Graphene Water Dispersion (2 wt%):
- Electronics:
- Conductive Inks and Coatings: Used for printed electronics, flexible circuits, and touchscreens.
- Transparent Conductors: Creates thin, conductive films for displays and solar cells.
