Effect of hydrophilicity of polyaniline particles on their

Popis výsledku v původním jazyce

Title: Effect of hydrophilicity of polyaniline particles on their electrorheology: Steady flow and dynamic behaviour 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 particles with silicone-oil medium, their interactions were limited and the viscosity of suspension was low. When the electric field was applied, the rigidity of the polarized chain structure of the particles increased and, consequently, viscosity increased as well. In the contrast, the field-off suspension viscosity of highly interacting hydrophilic particles, which are incompatible with the oil, was high especially at low shear rates, and the material had a pseudoplastic character.
