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 کاملPolymer blends, copolymers and networks. Scattering properties and phase behavior
The phase behavior and scattering properties of polymer blends, copolymers and networks in solution and in bulk are examined. The theoretical framework used here is based upon the extension of the random phase approximation to polymers proposed by de Gennes and its application to chains with various architectures. The case of blends containing stiff chains is considered and the effect of nemati...
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 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 ...
