This review provides detailed information on the synthesis, structure, properties, methods for studying, and areas of application conductive polymers synthesized basis phenylenediamines. Conductive based phenylenediamines are cationic salts highly conjugated by electrochemical or chemical oxidation. Chemical oxidative polymerization has led to formation various functional polymers. Depending re...

Electrorheological properties of suspensions are considerably affected by hydrophilicity of suspension particles. As a model material, polyaniline base powder protonated with sulfamic, tartaric, or perfluorooctanesulfonic acids provided particles of various hydrophilicity. The experiments revealed that, in the absence of electric field, due to a good compatibility of hydrophobic polyaniline par...

Monodisperse anisotropic particles have tremendous potentials in materials science and engineering (Hosein et al., 2010). As one of this kind of materials, snowman-like particles have drawn a special attention in the aspects of both their synthesis mechanism and applications. In this study, we synthesized micron-sized snowman-like poly(methyl methacrylate) (PMMA) particles via a seed emulsion p...

Emulsion stability is a fundamental determination for separation technologies. We use the critical electric field (CEF) and viscosity changes in DC electrorheological (ER) experiments in dynamic mode to establish the level of stability of water-in-crude oil emulsions previously studied through bottle tests. The CEF value corresponds to the value of electric field at which the current reaches 95...

The paper presents results of rheological experiments on viscosity under anisotropic pressure and in electric field of diethylene glycol-based MgAl2O4 nanofluids. Nanofluids have been prepared in a two-step method. The dynamic viscosity of nanofluids with various mass concentrations of nanoparticles was measured in the range of shear rates from 10 s -1 to 1,000 s -1 in constant temperature unde...
