Mean-field electrostatics is used to calculate the bending moduli of an electric double layer for fixed surface charge density of a macroion in a symmetric 1∶1 electrolyte. The resulting expressions for bending stiffness, Gaussian modulus, and spontaneous curvature refer to a general underlying equation of state of the electrolyte, subject to a local density approximation and the absence of dipole and higher-order fields. We present results for selected applications: the lattice-gas Poisson-Fermi model with and without asymmetric ion sizes, and the Poisson-Carnahan-Starling model.
平均场静电学用于计算宏观离子表面电荷密度固定的电双层的弯曲模量在对称的 1∶1 电解质中。得到的弯曲刚度、高斯模量和自发曲率表达式适用于电解质的一般基础状态方程，服从局部密度近似且不存在偶极子和更高阶场。我们给出了一些应用的结果：带有和不带有不对称离子大小的格子气泊松-费米模型，以及泊松-卡伦哈-斯塔林模型。
