Typical Data of Graphene Dispersion.*1

1. Graphene Purity : >99%

2. Lateral Size of Graphene (Counted Number of Flakes in TEM)

3. Number of Layers (Counted Number of Flakes using TEM)

• 1~10 Layers : >70%
• >30 Layers : <5%

4. Lateral Size of Graphene (Dynamic Light Scattering)

5. SEM

6. Raman Spectrum

Note

(*1). At 0.1mg/ml in NMP.

(*2). Dispersant is contained at 10wt% of graphene weight.

(*3). As graphene is dispersed, not dissolved, please stir with a rod well and sonicate the product in water bath before use.
