用Monte Carlo模拟方法研究了高电荷柔性聚阳离子和聚阴离子在带电圆柱基底上的吸附。提供了详细的结构研究，包括单体和流体电荷分布。聚阳离子和带负电荷的基板之间的短程吸引力的影响也被认为是。我们证明，多层结构的建立是高度禁止的，主要是由于强曲率下基底的低维度引起的高熵损失。
The adsorption of highly charged flexible polycations and polyanions on a charged cylindrical substrate is investigated by means of Monte Carlo simulations. A detailed structural study, including monomer and fluid charge distributions, is provided. The influence of a short-range attraction between the polycation and negatively charged substrate is also considered. We demonstrate that the building up of multilayer structures is highly prohibited mainly due to the high entropy penalty stemming from the low dimensionality of the substrate at strong curvature.
