The Local Structure of Miscible Polymer Blends
1. Introduction The formation of miscible mixtures of two chemically dissimilar polymers is in general unfavourable. For many materials a single phase is never formed, while for others, the miscible state is only obtained at low temperatures. The classic description of the interaction between two polymers is via the Flory-Huggins theory (for example see [l]) in which x, the interaction paramete...
متن کاملSurface segregation amplification in miscible polymer blends near criticality
– In atomic, small molecule or polymeric multicomponent materials, surface compositions naturally differ from the bulk because one component (or phase) will generally favor the surface region. Binary polymer blends represent a model system to investigate surface enrichment because segregation is enhanced by the small combinatorial entropy of mixing and amplified by chain connectivity (relative ...
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 کاملTests of mode coupling theory in a simple model for two-component miscible polymer blends
We present molecular dynamics simulations on the structural relaxation of a simple bead-spring model for polymer blends. The introduction of a different monomer size induces a large time scale separation for the dynamics of the two components. Simulation results for a large set of observables probing density correlations, Rouse modes, and orientations of bond and chain end-to-end vectors, are a...
متن کاملRelationship between the Glass Transition Temperature and the Interaction Parameter of Miscible Binary Polymer Blends
An equation that relates the g h transition temperature, TE, and a binary interaction parameter, x, for miscible binary polymer blends was derived. The equation including no adjustable parameters was based on a thermodynamic mixing formalism using enthalpy as the thermodynamic parameter. The enthalpy of mixing was written as a van Laar expression, and the T, was formally treated as a second-ord...
