Phase-Field Simulation of Polymer Crystallization during Cooling Stage

Xiaodong Wang and Jie Ouyang
Abstract—The phase-field method has been developed to simulate the crystal growth of semi-crystalline polymer during cooling stage by considering the effect of temperature on the nucleation density. It assumes that the nucleation mechanism is heterogeneous, and the relationship between the nucleation density and the temperature is described by an empirical function. The crystal growth after nucleation is modeled by a modified phase-field method which uses a non-conserved crystal order parameter to indicate whether the material is solid or liquid. By using the proposed model, the influence of cooling rate on the crystallization morphologies and crystallization kinetics has been investigated.

Index Terms—Polymer, crystallization, phase-field, cooling.
