Application

• Composites.
• Conductive inks.
• Electrodes for LiB.
• Energy storage & harvesting applications.
• Bio-medical applications.

Preparation Note

Preferred dispersing organic solvents: pyrrolidones and chlorinated solvents, also dispersible in acetone, ethyl acetate, dimethyl formamide, ethylene glycol, or 1,2-dimethoxyethane at concentration ≤0.1 mg/mL after bath sonication for 15 min with stability for a few hours.

• Less preferred dispersing organic solvents: cyclohexanone and γ-butyrolactone.
• Aqueous dispersions are possible at 0.1 mg/mL with triton-X-100, sodium cholate and deoxycholate and cellulose-based surfactants.
