Influence of temperature on the electrorheological effect

Popis výsledku v původním jazyce

The electrorheological (ER) fluids are suspensions that can alter their rheological parameters by means of external electric field strength variation. They undergo a transition from liquid-like to solid-like state, which is represented by a steep increase in viscosity. It is assumed that the major phenomena responsible for this behavior are conductivity of the particles, and dielectric relaxation strength [1] of the ER fluid representing the difference between relative permittivity at ?zero? and ?infinite? frequencies. In this study, the temperature dependent rheological behavior of prepared ER fluids based on carbonized aniline oligomers particles dispersed in silicone oil in the absence and in the presence of external electric field was examined. Impedance spectroscopy was used as an evaluative tool of the ER effect, and the Cole-Cole model was applied in order to obtain the values of dielectric parameters [2]. It was found that with increasing temperature, the relaxation times of pr
