一、双电层理论简介固体在水溶液中表面形成双电层而带电的现象是一种重要的表面现象,物理化学家们早就对此予以重视。 1853年Helmholtz提出了双电层的平板电容器模型。他认为双电层是由带电荷的固体表面与溶液中紧靠着固体表面的相反电荷部分所组成的一个微形平板电容器。但根据该模型计算出的一些双电层参数与实测值相差较大,说明平板电容器模型与实际情况有较大的差异。 1910年Gouy-Chapman提出了双电层的
First, the theory of electric double layer Introduction Solid surface in aqueous solution in the formation of electric double layer and charged phenomenon is an important surface phenomenon, physicists have long been paid attention to this. In 1853 Helmholtz proposed a double-layer flat-panel capacitor model. He believes that the electric double layer is a micro-plate capacitor consisting of a charged solid surface and an oppositely charged portion of the solution in the immediate vicinity of the solid surface. However, some of the parameters of the electric double layer calculated by the model differ greatly from the measured values, indicating that there is a big difference between the model of the plate capacitor and the actual situation. 1910 Gouy-Chapman presents the electric double layer
