Computer Modeling and Simulation for 3D Crystallization of Polymers. I. Isothermal Case

Computer modeling and simulation for 3D isothermal crystallization of polymers is presented. We use the pixel coloring method to capture the morphology evolution and calculate the crystallization kinetics. A parametric study is used to explore the influences of nucleation density and growth rate on the crystallization. Results indicate that nucleation density is a significant factor to the crystallization kinetics as well as the morphology; growth rate only affects the crystallization kinetics and has no impact on the final morphology. Present results are hoping to give more insight about the crystallization and be more helpful to the industrial application.
