【 摘 要 】

Electrorheological fluids based on polydimethylsiloxane filled with halloysite nanotubes were studied. The fillerstructure was characterized by TEM, SEM, and X-ray diffraction. When an electric field is applied to suspensions, their rheologicalbehavior changes – the contribution of the elastic component becomes significant and samples behave like a solidbody. The effect of the electric field and filler concentration on the electrorheological behavior was investigated. The influenceof water content on the filler structure, as well as on electrorheological and electrophysical properties of suspensions, wasconsidered. Electrorheological fluids filled by halloysite with small water content exhibit slightly higher rheological characteristicsunder an electric field than dried ones. This study shows the prospects of using halloysite nanotubes as a dispersedphase for electrorheological fluids.
