Influence of the hydrocarbon chain length of imidazolium-based ionic liquid on the dispersion and stabilization of double-walled carbon nanotubes in water

- Synthesis of imidazolium-based ionic liquids from natural compounds (fatty acids).
- Stabilization of 50 mg/L double walled carbon nanotubes in water up to 20 days.
- Dispersibility increased with increasing the length of the hydrocarbon chain.
