Interlocked-ring polymers, also known as polycatenanes, possess an interesting molecular architecture. These polymers are composed of many interlocked rings in a linear chain. The topological constrain between neighboring rings distinguishes the interlocked-ring polymer from its linear counterpart. Here we present extensive molecular dynamic simulations on the interlocked-ring polymers and analyze the static properties of the polymer. By applying external forces to the polymer, we also study the force-extension curves of the polymer, which provides rich information about the mechanical properties of the interlockedring polymers.

互锁环聚合物的力学性能：分子动力学模拟研究

互锁环聚合物，也称为聚catenanes，具有有趣的分子结构。这些聚合物由线性链中许多互锁的环组成。相邻环之间的拓扑约束将互锁的环聚合物与其线性对应物区分开。在这里，我们对互锁环聚合物进行了广泛的分子动力学模拟，并分析了聚合物的静态特性。通过对聚合物施加外力，我们还研究了聚合物的力-延伸曲线，该曲线提供了有关互锁环聚合物的机械性能的丰富信息。
