Molecular Dynamics Simulation of Cold Crystallization Behavior of Polyethylene Polymers
In this paper,molecular dynamics simulations are used to study the cold crystallization behavior of two amorphous polymer systems quenched at different initial temperatures during the same heating process.The changes of crystallinity,bond orien-tation,stem length and crystal morphology of the polymer system during the cold crystallization process are studied,and it is found that the system with a higher initial temperature crystallizes earlier than the system with a lower temperature before quenching,and the results are consistent with the experimental observations in the literature.
