polymer在平坦均匀表面上的连续随机顺序吸附

Continuum random sequential adsorption of polymer on a flat and homogeneous surface

Michał Cieśla

摘要:

本文系统地研究了聚合物的随机序列吸附(RSA)过程。为了精确控制各向异性和自由度的数量,使用了两种不同的聚合物。在第一种情况下,单体沿直线放置,而在第二种情况下,颗粒的相对取向是随机的。这样的聚合物随机地填充平坦均匀的表面。本文重点研究了最大随机覆盖率和吸附动力学对聚合物尺寸、形状各向异性和自由度的依赖性。所得结果进行了讨论,并与其他数值实验和理论预测进行了比较。

英文摘要:

Random sequential adsorption (RSA) of polymer, modeled as a chain of identical spheres, is systematically studied. In order to control precisely anisotropy and number of degrees of freedom, two different kinds of polymers are used. In the first one, monomers are placed along a straight line, whereas in the second, relative orientations of particles are random. Such polymers fill a flat homogeneous surface randomly. The paper focuses on maximal random coverage ratio and adsorption kinetics dependence on polymer size, shape anisotropy, and numbers of degrees of freedom. Obtained results were discussed and compared with other numerical experiments and theoretical predictions.
