Predicting the Flory-Huggins χ Parameter for Polymers with Stiffness Mismatch from Molecular Dynamics Simulations
The Flory–Huggins χ parameter describes the excess free energy of mixing and governs phase behavior for polymer blends and block copolymers. For chemically-distinct nonpolar polymers, the value of χ is dominated by the mismatch in cohesive energy densities of the monomers. For blends of chemically-similar polymers, the entropic portion of χ, arising from non-ideal local packing, becomes more si...
متن کاملFlory-Huggins theory for athermal mixtures of hard spheres and larger flexible polymers.
A simple analytic theory for mixtures of hard spheres and larger polymers with excluded volume interactions is developed. The mixture is shown to exhibit extensive immiscibility. For large polymers with strong excluded volume interactions, the density of monomers at the critical point for demixing decreases as one over the square root of the length of the polymer, while the density of spheres t...
متن کاملPressure dependence of the Flory-Huggins interaction parameter in binary polymer blends investigated by SANS
The pressure dependence of the Flory Huggins interaction parameter of two binary polymer blends was investigated by small angle neutron scattering (SANS). We studied the polymer blends deutero PoIystyrene / Polyvinylmethylether (d PS / PVME) and deutero Polystyrene / Polyphenylmethylsiloxane (d PS / PPMS), exhibiting decomposition at high and at low temperatures, respectiveIy. In both cases the...
متن کاملFlory theory for polymers.
We review various simple analytical theories for homopolymers within a unified framework. The common guideline of our approach is the Flory theory, and its various avatars, with the attempt at being reasonably self-contained. We expect this review to be useful as an introduction to the topic at the graduate student level.
متن کاملElastic properties of photoswitchable azobenzene polymers from molecular dynamics simulations.
Nanomechanical devices or molecular machines will, for a broad range of applications, most likely be powered by light or other kinds of electromagnetic radiation. The major reasons are ease of addressability, picosecond reaction times to external stimuli, and compatibility with a broad range of ambient substances, such as solvents, electrolytes, or gases. Azobenzene is a well-studied photoactiv...
