Technology of Few-Layer Graphene Production
Our few-layer graphene dispersions are obtained through a patented method that involves the dispersion of graphite at resonant frequencies.
Resonance is a physical phenomenon in which a system begins to oscillate with maximum amplitude in response to an external force with a certain frequency that matches its own (natural) frequency.
Acoustic resonance generates strong vibrational waves in the dispersion medium. These vibrations are efficiently transferred to the graphite particles, causing intense mechanical stress.
We chose this method of graphene production based on theoretical assumptions regarding the differences in properties between elemental and few-layer graphene.
During resonance treatment in aqueous solutions of metal salts, graphene becomes intercalated with H₃O⁺ ions and metal cations, particularly Mg²⁺. This expands the interlayer distance between the graphene sheets by almost a factor of three, leading to an increase in ion mobility.
1. Advantages of Few-Layer Graphene Compared to Elemental Graphene
Structural Stability
Our few-layer graphene has much greater mechanical strength and resistance to damage due to interlayer van der Waals interactions
Improved Conductivity
Our few-layer graphene maintains high conductivity but is less prone to degradation when in contact with polymers
Better Dispersibility
Our few-layer graphene has an optimal balance between specific surface area and interlayer forces, improving its dispersibility
2. Effect of Dispersion Media Containing Few-Layer Graphene
Synergistic Effect with the Matrix
Using dispersion media that contain components of the future composite creates direct chemical compatibility
Reducing Post-Processing
If few-layer graphene is already in a compatible environment, there is no need to remove solvents and then re-disperse it
3. Role of Acoustic Resonance Method in Dispersion
Minimization of Defects
Acoustic resonance allows for the gentle separation of graphite into few-layer fragments without damaging the carbon lattice structure
High Homogeneity
The acoustic resonance method helps achieve a narrow distribution of the number of graphene sheet layers
Control Over Morphology
Our acoustic resonance method can be controlled to achieve different sizes and shapes of graphene sheets
