Product Description:
An ultrasonic probe dispersion equipment operates based on the cavitation effect of ultrasound, which generates microscopic bubbles in a liquid. Under the action of ultrasonic waves, these bubbles rapidly expand and contract, eventually collapsing and producing intense shockwaves. These shockwaves exert physical impact on graphene layers, causing them to separate from their originally stacked state and achieving dispersion. Simultaneously, ultrasound enhances the interaction between the dispersion medium and the graphene, further improving the dispersion effectiveness.

FAQ:
How does an ultrasonic probe dispersion equipment disperse graphene?
For the dispersion and emulsification of graphene, ultrasound utilises cavitation in liquid to break down tens of layers of graphene into just a few layers, or even a single layer. With some process modifications to existing equipment, companies can meet their production or usage requirements.
How to conduct a graphene slurry breaking and dispersion experiment using an ultrasonic probe dispersion equipment?
Experimental Preparation
Wy1: Graphene and Si ethylene glycol slurry (approx. 220 mL). Control slurry temperature below 100°C and ensure no water or impurity contamination.
Wy2: Graphene in ethylene glycol slurry (approx. 130 mL). Ensure no water or impurity contamination.
100 mL beaker: For auxiliary experimental operations.
Ultrasonic probe dispersion equipment: Probe size and power directly affect ultrasonic energy output. Select appropriate models based on processing volume.
Ethylene glycol: Used as the slurry solvent. Its low toxicity and moderate viscosity effectively transmit ultrasonic energy while preventing graphene re-agglomeration.
Experimental Procedure
Using the dispersion of graphene in ethylene glycol as an example, the feasibility of ultrasonic dispersion technology was verified. Suitable ultrasonic equipment for different scales and graphene types is recommended.
Wy1: Ultrasonically break down graphene particles and uniformly disperse them with Si. Monitor equipment parameters and slurry particle size. The final median particle size (D50) should be approximately 0.5 μm, with no stratification after standing. Record parameters and time when D50 reaches ~5 μm and ~1 μm.
Wy2: Ultrasonically break down and disperse graphene particles. Monitor equipment parameters and slurry particle size. The final D50 should be approximately 0.5 μm. Record parameters and time when D50 reaches ~5 μm, ~1 μm, and ~0.5 μm.
Results and Analysis
After optimisation, both Wy1 and Wy2 slurries achieved D50 ≈ 0.5 μm with no significant stratification after 24 hours of standing. In Wy1, silicon particles and graphene were uniformly dispersed, indicating that ultrasound not only broke down graphene aggregates but also promoted homogeneous mixing of the two materials. The results demonstrate that ultrasonic treatment achieved uniform graphene dispersion in both slurries, with no noticeable re-agglomeration.
