Mesoscale Simulations of the Polymer Blends Based on the Mesoscopic Dynamic Method

The mesoscale simulation of polymer blends, Polypropylene (PP) and Polyamide12 (PA12), was calculated by Mesoscopic Dynamic method (MesoDyn). The free energy density, the order parameters and the density profiles were got by the simulation. The evolvement of the phase status was analyzed based on the free energy density and the order parameters. Using density profiles, the kinetics of phase separation was examined and the phase separation behavior was observed. Results showed that mesoscale simulation can be used to determine phase separation of sparingly miscrible polymer blends.
