Molecular Dynamic Simulations on the Compatibility of PP/PA12 Blends
The compatibilities of polymer blends, Polypropylene(PP) and Polyamide12(PA12), was simulated by molecular dynamics(MD) simulations. Density, cohesive energy density (CED) ,and solubility parameters(δ) of pure substances and PP/PA12 blends were calculated by MD simulations with the COMPASS force field for the prediction of polymer blends compatibility . Results showed that PP/PA12 is not miscri...
متن کاملDynamic Heterogeneity in Fully Miscible Polymer Blends through Molecular Simulations
SUMMARY: The effect of self-concentration and intermolecular packing on the dynamics of polymer miscible blends is examined by extensive atomistic simulations. Direct information on local structure of the blend system allows a quantitative calculation of selfand effective composition terms at various length scales that are introduced to proposed models of blend dynamics. Through a detailed stat...

متن کاملThermodynamics of Polymer Blends 2
This chapter summarizes the thermodynamics of multicomponent polymer systems, with special emphasis on polymer blends and mixtures. After a brief introduction of the relevant thermodynamic principles – laws of thermodynamics, definitions, and interrelations of thermodynamic variables and potentials – selected theories of liquid and polymer mixtures are provided: Specifically, both lattice theor...
متن کاملConfined flow of polymer blends.
The influence of confinement on the steady-state morphology of two different emulsions is investigated. The blends, made from polybutene (PB) in polydimethylsiloxane (PDMS) and polybutadiene (PBD) in PDMS, are sheared between two parallel plates, mostly with a standard gap spacing of 40 microm, in the range of shear rates at which the transition from "bulk" behavior toward "confined" behavior i...
