Preparation Note

Electric Arc Discharge Method
Procedure for dispersion of this PEG-functionalized SWNTs product in water:
Typically after this procedure, the material is completely dispersed according to visual observation.
Sonicate 50 mg of material in 5 mL water for 30 min. (A bath sonicator with a sonic power between 45 W and 270 W works fine. A sonic power of 270 W is preferable for faster dispersion).
Add 45 mL of water and sonicate for additional 60 min (or until the material appears well-dispersed).
Dilute the dispersion to the desired concentration and sonicate if necessary. If aggregates are still visible continue to sonicate until satisfactory dispersion is obtained. Note: If unable to achieve a satisfactory dispersion, reduce the initial amount of 50 mg of material in 5 mL of water.
This procedure is to be used as a basis and additional procedures can be researched. Results may vary if this is the first time working with this material. Solubility of this PEG-functionalized SWNTs product can reach 5.0 mg/mL in water.
