Rheology of Binary Polymer Blends under External Electric Fields

چکیده
We investigate the relation between the structures of domains and the increase of stress under imposed electric field by performing simulations of the system composed of two kinds of fluids inserted between two plates of electrodes. It is found that the stress is significantly increased under applied electric fields as compared with the one of system under no external field. Under shear flows we also find that the elongated domains are broken up at slip regions. The spatial distribution of the three stresses: (a) Maxwell stress, (b) stress coming from surface tension and (c) Newtonian stress to the total stress is strongly related to the local domain structure.

In this study, the compatibility of the blends of polypropylene (PP) and polybutene-1(PB-1) homopolymer before and after long chain branching process were studied. The blends were prepared and long-chain branched directly via reactive extrusion process in presence of free radical initiator and trimethylolpropane tri methacrylate (TMPTMA) poly functional monomer. The optimum percentage of TMPTMA...

PP-g-PS copolymer is a typical compatilizer used in polypropylene and polystyrene immiscible blends. PP-g-PS copolymers with different side chain lengths were synthesized, and their thermal and mechanical properties were characterized by differential scanning calorimetry (DSC), polarizing optical microscopy (POM) and dynamic mechanical analysis (DMA), respectively. The DSC and POM results show ...
متن کاملInterfacial slip in sheared polymer blends.
We have developed a dynamic self-consistent field theory, without any adjustable parameters, for unentangled polymer blends under shear. Our model accounts for the interaction between polymers, and enables one to compute the evolution of the local rheology, microstructure, and the conformations of the polymer chains under shear self-consistently. We use this model to study the interfacial dynam...
متن کاملRheology and Morphology Development in Immiscible Polymer Blends
In this review, progress towards a fundamental understanding of the rheologymorphology relationship in immiscible polymer blends is discussed. The behaviour of biphasic polymer fluids, containing Newtonian components and subjected to simple shear flows is relatively well understood at present. The behaviour of these “simple” blends will be discussed first, as it serves as a reference for the ot...
