前言静电型憎液胶体的稳定性是胶体化学中最重要的问题之一。本世纪四十年代以来,DLVO理论对此做了较园满的解释。Verwey和Overbeek对扩散双电层排斥能的计算给出了正确的方程,当颗粒之间的距离不同时,对不同表面电位的颗粒之间的排斥能做过计算[1]。Hamaker[2]首先根据原子或分子之间范德华力的加和性导出颗粒之间吸引能的方程。因此,可以认为,根据颗粒之间的总位能曲线来讨论胶体的稳定性问题,从理论上已经基本上解决了。
Introduction The stability of the electrostatic hydrophobic liquid colloid is one of the most important problems in colloidal chemistry. Since the 1940s, DLVO theory has done a more full explanation. Verwey and Overbeek’s calculation of the repulsive energy of a diffused electric double layer gives the correct equation. When the distances between particles are different, the repulsion between particles with different surface potentials can be calculated [1]. Hamaker [2] first derived the attraction energy equation between particles based on the van der Waals forces between atoms or molecules. Therefore, it can be considered that the discussion of the colloidal stability problem based on the total potential energy curve between particles has been basically solved theoretically.
