We use a continuum chain model and develop an analytical theory for the interaction between many spheres immersed in a fluid of ideal polydisperse polymers. Assuming local spherical symmetry of the polymer field about each particle, combined with a local approximation, compact expressions are derived for the many-body interaction between the spheres. We use a mean-field approximation to investigate the fluid-fluid phase diagram for the mixture.
我们使用连续链模型并为理想多分散聚合物中的多个球体的相互作用开发了一种分析理论。假设聚合物场在每个粒子周围具有局部球形对称性,并结合局部近似,推导出了球体之间多体相互作用的紧凑表达式。我们使用平均场近似来研究混合物的流体-流体相图。
