In this Letter, we present a self-consistent field theory of macroscopic forces in spatially inhomogeneous flexible chain polyelectrolyte solutions. We derive an analytical expression for a stress tensor which consists of three terms: isotropic hydrostatic stress, electrostatic (Maxwell) stress, and stress rising from conformational entropy of polymer chains -- conformational stress. We apply our theory to the description of polyelectrolyte solutions confined in a conductive slit nanopore and observe anomalous behavior of disjoining pressure and electric differential capacitance.

不均匀聚电解质溶液中的宏观力

在这封信中，我们提出了空间不均匀柔性链聚电解质溶液中宏观力的自洽场论。我们推导出应力张量的解析表达式，它由三个项组成：各向同性静水应力、静电（麦克斯韦）应力和聚合物链构象熵产生的应力——构象应力。我们将我们的理论应用于描述限制在导电狭缝纳米孔中的聚电解质溶液，并观察分离压力和电微分电容的异常行为。
