Single-Layer Graphene Oxide Powder 10 g Research ATOMFAIR®

This oxygen-functionalized two-dimensional carbon material requires controlled storage to prevent moisture uptake and aggregation. Dispersion stability depends on solvent polarity and processing conditions.

• Dispersion Medium Compatibility: The hydroxyl, carboxyl, and epoxy groups enable dispersion in water and polar organic solvents, but non-polar solvents may cause poor exfoliation.
• Storage Sensitivity: Freeze-dried powder should be stored in a sealed container under dry, ambient conditions to avoid rehydration and aggregation.
• Processing Route Consideration: Film formation or functionalization requires confirmation of dispersion medium and downstream material system before use.

This procedure describes the preparation of a stable aqueous dispersion from single-layer graphene oxide powder. Proper dispersion is critical for downstream film-forming or functionalization research.

Required Equipment: Analytical balance, Ultrasonic bath or probe sonicator, Glass vial or beaker

1. Weigh the powder
   Weigh the desired amount of single-layer graphene oxide powder using an analytical balance in a dry environment.
2. Transfer to container
   Transfer the weighed powder into a clean glass vial or beaker.
3. Add dispersion medium
   Add deionized water or a polar organic solvent to the powder at the target concentration.
4. Disperse via sonication
   Sonicate the mixture in an ultrasonic bath or with a probe sonicator for 10–30 minutes until a homogeneous dispersion is obtained.
5. Verify dispersion quality
   Visually inspect the dispersion for absence of visible aggregates before use in further processing.
