Description
Graphene Nanoflakes (GNFs) are ultra-thin, micron- to nano-sized platelets derived from high-quality graphene sheets. Engineered for superior electronic, mechanical, and thermal performance, GNFs combine the advantages of pristine graphene with a process-friendly flake morphology, making them highly versatile for industrial, scientific, and advanced technological applications.
Structure & Composition
Graphene nanoflakes consist of:
- Few-layer graphene sheets (typically 1–10 layers)
- Lateral dimensions ranging from 20 nm to several micrometres
- High edge density, enabling accelerated surface reactions
- Purity levels up to 99% carbon, depending on grade
This unique combination of large surface area, atomic thickness, and abundant edge sites makes GNFs exceptionally active and dispersible.
Key Features & Properties
- Ultra-high surface area (500–900 m²/g)
- Excellent electrical conductivity
- Superior mechanical stiffness and flexibility
- Thermal stability > 600°C in inert conditions
- Active edge sites for enhanced functionalization
- Easy integration in polymer, metal, and ceramic matrices
- Stable dispersion in water and organic solvents (functionalized grades available)
Advantages of Graphene Nanoflakes
- Enhanced electron transport pathways for batteries and supercapacitors
- Improved mechanical reinforcement in composites
- High catalytic activity due to exposed graphene edges
- Boosted thermal and electrical performance in coatings and adhesives
