Dispersing single-walled carbon nanotubes using common phospholipids with a small amount of polyethylene glycol-phospholipid additives

- Dispersion isotherms of single-walled carbon nanotubes were obtained.
- 5 μmol/L of poly(ethylene glycol)-phospholipid was sufficient.
- Adsorbed molecules, not vesicles, are responsible for dispersion.
- The shorter chain phosphatidylcholine disperses better.
- Glycerol-phospholipid is the most efficient host.
