Numerical Studies of Phase Separation in Models of Binary Alloys and Polymer Blends
We review some recent results concerning numerical studies of the CahnHilliard equation in three dimensions to describe the phase separation process in a mixture after a quench within the coexistence curve. We focus on the late time behavior for two experimentally relevant systems: binary alloys and binary polymer blends. We find that, in both systems, dynamical scaling with a time dependent ch...

متن کاملConjugated-Polymer Blends for Optoelectronics
Solution-processed polymer optoelectronic devices such as light-emitting diodes and solar cells have many advantages for large-area manufacture, and show increasing levels of performance. Here, we review recent progress in using blends of two conjugated polymers for optoelectronic devices. The blending of two or more polymers allows tuning of device performance, and for photovoltaics presents a...
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...
