What is Zeta Potential?

What is Zeta Potential?

Zeta potential refers to the electric potential of charged particles (such as colloidal particles, emulsion droplets, etc.) in a dispersed system at the slipping plane. The slipping plane is the imaginary boundary between the liquid layer (fixed layer) adsorbed on the particle surface and the surrounding movable liquid. It reflects the interaction strength between the particle surface charge and the surrounding dispersion medium (such as liquid). It is a key parameter for characterizing colloidal stability and the behavior of dispersed systems
