WebNov 18, 2024 · Ionic effects of the DLCs have sometimes been thought to be expressed by the Gouy–Chapman (GC) theory, which exhibits V-shaped capacitance vs. voltage curves. However, no V-shape has been found even in 0.05-mM salts [ 12 ]. DLC values have not been obeyed by the dependence of the square-root of concentrations predicted from the … WebThe curves do not involve a valley shape of Gouy–Chapman (GC)-Stern's type until ionic concentrations are less than 0.05 mM, because measured capacitance is controlled by the inner layer. The valley shape at low concentrations can be measured in deionized sulfonic latex suspensions, whose conductance is brought about by the ionic latex ...
