论文摘要
在本文中，我们提出了在空间不均匀柔性链聚电解质溶液中宏观力的自洽场理论。我们得出应力张量的分析表达，该分析表达式包括三个术语：各向同性静水压力，静电（麦克斯韦）应力以及从聚合物链的构象熵升高的应力 - 构象应激。我们将理论应用于限制在导电狭缝纳米孔中的聚电解质溶液的描述，并观察到压力和电差电容的异常行为。
In this paper, 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.
