"The project focuses on the research of lamellar and ring structures formed during the flow of suspensions in electric field and their dependence on dispersed particles shape and size, DC and AC electric conductivity and dielectric properties determining the particles polarizability. For this purpose, model suspensions of electrically conducting polymers (polyaniline and polypyrrole protonated to various degrees) and suspensions of inorganic materials of different particle geometry and chemical nature (silica, mica, graphite, ferrites, montmorillonite, carbon nanotubes) coated with these polymers will be prepared. The results of the project will contribute to the elucidation of the mechanisms of breaking these structures by shear forces in the flow field and will support the possibility of designing electrorheological suspensions with efficiency acceptable for practical applications."@en . .
