Zeta (ζ) Potential for Micelle and Microemulsion
Measurement of zeta potential is not applicable to systems with entangled particles, non-charged particles, and concentrated solutions where the interfacial electrical double layers are depressed. However, dispersibility of charged colloidal particles in aqueous solution can be evaluated by ζ potential. Therefore, this chapter deals with the basics of electrical interface phenomenon and its relationship between surface electric potential, zeta potential, and surface charge density.
