Dynamic density functional theory for entangled polymer mixtures

The dynamic density functional (DDF) theory is an efficient method to

study the dynamic evolution of inhomogeneous polymer and block

copolymer melts. It builds on the self-consistent field (SCF) theory,

one of the most successful mean-field theories for such polymer

systems at equilibrium. We have recently developed an approach to

systematically construct DDF theories from microscopic reference

simulation trajectories. Using this method, to develop a DDF theory

for entangled polymer mixtures. We discuss the crossover from the

Rouse to the reptation regime, and the impact of entanglements on the

ordering kinetics of copolymers and the demixing dynamics of

homopolymer blends.
