采用连续自洽场理论，数值研究了具有弥散电荷分布的柔性聚乙烯（PE）在溶液中的相反电荷球上的吸附。边界层厚度与表面电荷密度和PE链的电荷分数之间的幂律标度关系与已有的分析结果一致。研究了曲率效应对吸附PE链上电荷总量相对于表面电荷的电荷补偿程度的影响，并根据表面电荷密度和PE链上电荷分数对电荷补偿程度的依赖关系，对曲率效应有了清晰的认识。
The adsorption of flexible polyelectrolyte (PE) with the smeared charge distribution onto an oppositely charged sphere immersed in a PE solution is studied numerically with the continuum self-consistent field theory. The power law scaling relationships between the boundary layer thickness and the surface charge density and the charge fraction of PE chains revealed in the study are in good agreement with the existing analytical result. The curvature effect on the degree of charge compensation of the total amount of charges on the adsorbed PE chains over the surface charges is examined, and a clear understanding of it based on the dependences of the degree of charge compensation on the surface charge density and the charge fraction of PE chains is established.
