逾渗团簇上的环状聚合物

Ring polymers on percolation clusters

K. Haydukivska, V. Blavatska

摘要:

在目前的工作中,环状聚合物链(环)在结构无序的环境中(例如在交联聚合物凝胶中)利用模型的封闭自回避行走(SAW)轨迹上$d=3$维渗流集团进行了研究。应用枢轴算法进行了数值模拟。得到了典型高分子构象的普遍尺寸和形状特征,如尺寸比、平均非球面度和长轴度的估计。我们的结果定量描述了与纯溶剂相比,环状聚合物在无序环境中的伸长和各向异性的增加。

英文摘要:

In the present work, the cyclic polymer chains (rings) in structurally disordered environment (e.g. in the cross-linked polymer gel) are studied exploiting the model of closed self-avoiding walks (SAWs) trajectories on $d=3$-dimensional percolation clusters. Numerical simulations with an application of pivot algorithm are performed. The estimates for the universal size and shape characteristics such as size ratios, averaged asphericity and prolateness of typical polymer conformation are obtained. Our results quantitatively describe an elongation and increase of anisotropy of ring polymers in disordered environment comparing with the pure solvent.
