- a surfactant In order to disperse inorganic fine particles in a solvent or to disperse one of incompatible materials such as water and oil in the other, a surfactant is generally used. However, particularly when solid inorganic fine particles are dispersed in a solvent, the inorganic fine particles may settle during storage. Accordingly, as such a surfactant, a surfactant having a high surface activity is preferable in order to ensure the stability of the dispersion.
- a so-called synthetic surfactant is used rather than a natural soap component such as a long-chain fatty acid salt in view of its high surfactant activity and production cost.
- an anionic surfactant is used together with a water-soluble polymer in order to disperse carbon nanotubes in water.
- urea and a surfactant such as an alkyl sulfate ester salt are used in combination for the same purpose.
