Аннотация: In this study, an electrorheological effect of the suspensions containing porous chitosan particles in olive oil in a wide range of electric fields is reported. Porous chitosan particles were produced by freeze-drying. The structure of the filler was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, and X-ray scattering. Electrorheological behavior of low-filled fluids (0.1, 0.2, 0.5, and 1.0 wt %) was studied in shear and oscillation modes. Rheological data were fitted by Bingham, Cho−Choi−Jhon, and Seo−Seo models. Conductivity measurements were carried out to characterize the electrophysical properties of studied fluids. Polarization processes were considered from the standpoint of the Cole−Cole equation. Natural biodegradable materials such as chitosan and olive oil were used as components. The fluids showed high response to electric field and stable cyclic operation in on/off mode at extremely low concentrations. The yield stress reaches about 100 Pa for a 1 wt % suspension under an electric field of just 1 kV/mm. The sedimentation stability of the samples dramatically increases when the percolation threshold is passed. The sedimentation ratio at 1 wt % of the filler content remains at the level of 90% after almost a month. Thus, suspensions were considered as an alternative to typical silicon oil-based electrorheological fluids.
