How does the thickness range of ~1–5 nm affect the performance of WS2 in catalysis or optoelectronics?
The thin-layer WS2 nanosheets (thickness ~1–5 nm) correspond to few-layer material, which offers high surface area and a thickness-dependent bandgap suitable for catalytic and optoelectronic applications. The dispersion is supplied at 1 mg/mL in water with LiOH as a stabilizer, maintaining a pH of 8–9 to prevent aggregation and ensure uniform film deposition.
Can this aqueous WS2 dispersion with LiOH stabilizer be mixed with organic solvents or polymers?
The dispersion is formulated in water with LiOH at pH 8–9, making it directly compatible with water-soluble polymers and surfactants. Direct mixing with organic solvents may cause aggregation; solvent exchange or lyophilization is recommended for non-aqueous systems. The basic pH should be considered when integrating with pH-sensitive substrates or reagents.
What safety and storage precautions are required for this LiOH-stabilized WS2 dispersion?
The dispersion contains LiOH as a stabilizer, giving a pH of 8–9, which is mildly basic. Use gloves and goggles to avoid skin or eye irritation. Store in a sealed container away from light and CO₂ to prevent pH drift and destabilization. The product is supplied at 1 mg/mL in a 100 mL package; avoid freezing.
Atomfair Thin-layer Nano WS2 Dispersion with LiOH provides ~1-5nm thick nanosheets at 1mg/mL in water with pH 8-9, suitable for solution-processed thin-film and catalytic applications requiring aqueous dispersion stability.
Positive
- Ultrathin nanosheet thickness: The ~1-5nm thickness provides high specific surface area and potential quantum confinement effects, beneficial for thin-film deposition and catalysis.
- LiOH-stabilized alkaline dispersion: The LiOH stabilizer maintains pH 8-9, enhancing colloidal stability and preventing aggregation of WS2 nanosheets in aqueous media.
Trade-offs
- Low concentration limits mass yield: At 1 mg/mL, the dispersion requires larger volumes per experiment, and the 100 mL bottle yields only 100 mg total solid, which may be insufficient for bulk applications.
- Aqueous solvent restricts compatibility: The water-based solvent limits direct use with hydrophobic substrates or organic solvents, necessitating additional surface treatment or solvent exchange for certain processing routes.
