Electrokinetic Phenomenon - Sponge Sponge

When relative motion is applied between the two phases at a liquid-liquid or liquid-solid interface, a potential difference is generated along the direction of motion (streaming potential, sedimentation potential), and when a potential difference is applied along the interface, relative motion occurs between the interfaces (electrophoresis, electroosmosis). These four types of phenomena are collectively called interfacial electrokinetic phenomena.

液-液あるいは液-固界面において両相間に相対運動を与えると，運動方向にそって電位差を生じたり(流動電位，沈降電位)，界面にそって電位差を与えると界面間に相対運動(電気泳動，電気浸透)が起こる．これら4種類の現象を総称して界面動電現象という．
