Mechanical Properties of Interlocked-ring Polymers: A Molecular Dynamics Simulation Study

摘要

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 interlockedring 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.
