Abstract The random phase approximation for polymer blends was developed by H. Benoît and described small angle scattering functions as well mean field boundaries. It is a pure theory that loses validity close to the real boundaries due strong fluctuations. However, it gives very clear roadmap about diagrams functions. A simplification of discussed comes into effect when several polymers are mi...

Pickering emulsions are emulsions whose drops are stabilized against coalescence by particles adsorbed at their interface. Recent research on oil/water/particle systems shows that particles can sometimes adsorb at two oil/ water interfaces. Such “bridging particles” can glue together drops of oil in water or vice versa. We hypothesize that the same effect should apply in immiscible polymer blen...

Polymer-based coatings are a long-established category of protective for metals and alloys regarding corrosion inhibition. The polymer films can degrade, when coated on metallic substrates, the degradation facilitates moisture oxygen penetration, reducing film’s adhesion to substrate exposing extreme conditions capable corrosion. For this reason, pigments, inhibitors, other compatible blends ad...

The impact of phase morphology in electrically conducting polymer composites has become essential for the efficiency of the various functional applications, in which the continuity of the electroactive paths in multicomponent systems is essential. For instance in bulk heterojunction organic solar cells, where the light-induced electron transfer through photon absorption creating excitons (elect...

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...

Heterogeneous textures due to phase separation in molten polypropylene (PP)/ ethylene-propylene-rubber (EPR) blends were investigated in relation to their dynamic viscoelastic properties. As characteristic to heterogeneous liquids, slow relaxation mechanisms due to the existence of such phases were found for dynamic moduli of PP/EPR blends. These moduli were analyzed by using the linear viscoel...

Dilution of contact, hard sphere-like, nanoparticle-nanoparticle interactions upon mixing plays a key role in explaining nanoparticle dispersion in athermal all-polymer nanocomposites, as illustrated for polystyrene-nanoparticle/linear-polystyrene blends as a model system.
