The demulsification mechanism of PAMAM belongs to displacing mechanism. Acylamino groups of PAMAM of integral having strong polarity can take place chemical adsorption with the materials of strong polarity in the exterior of oil drop and be participated in into the membrane, which will result in adsorbed crude surfactant and other active materials to be partially displaced and reduce the intensity of interfacial film between oil and water.

其机理是由于整代的PAMAM具有强极性的酰胺基团，能与油滴表面的强极性的物质发生化学吸咐作用，参与成膜，能把原来吸咐的天然活性剂分子和其它活性物质部分顶替，削弱油水界面膜强度。
