Why is the product labeled 'Few Layers WS2 Dispersion' when the single-layer ratio exceeds 90%?
The product is named Few Layers but the technical specification confirms a single-layer ratio >90%, meaning the dispersion consists predominantly of monolayer WS2 sheets. Researchers should refer to the single-layer ratio specification rather than the product name for the precise layer count.
What is the function of LiOH as a stabilizer in this aqueous WS2 dispersion?
LiOH is used as a stabilizer to maintain the pH of the dispersion between 8 and 9, which is specified to ensure the WS2 dispersion remains stable in water.
This few-layer WS2 dispersion delivers >90% single-layer content in a water-based LiOH-stabilized medium at pH 8-9, offering high exfoliation yield for 2D materials research but requiring pH compatibility assessment for downstream processes.
Positive
- High single-layer ratio: With >90% single-layer content, this dispersion provides efficient exfoliation and uniform few-layer material, critical for reproducible device fabrication and spectroscopic studies.
- Alkaline-stabilized dispersion: LiOH stabilizer maintains pH 8-9, reducing particle aggregation and extending shelf life compared to neutral or unbuffered aqueous dispersions.
Trade-offs
- Alkaline pH sensitivity: The basic pH (8-9) may degrade acid-sensitive ligands, substrates, or biological matrices, requiring compatibility testing before integration.
- Fixed dilute concentration: At 1 mg/mL in 500 mL, the total mass is only 500 mg; applications requiring higher material throughput may need multiple bottles or concentration steps.
