Abstract Magnetorheological fluids are obtained on the basis of star-shaped and linear PDMS containing 70, 75, and 80 wt % of carbonyl iron microparticles. While pure PDMS polymers are Newtonian fluids, composites exhibit pseudoplasticity. The viscoe

Magnetoactive elastomers based on polydimethylsiloxane functional oligomers with a concentration of magnetic iron microparticles of 70, 75, and 80 wt % are synthesized. Soft samples with low (about 2 kPa) elastic moduli are obtained by introducing si

The conformational behavior of a single semiflexible polymer chain with a variable fraction of polar groups (dipoles) is studied by the molecular dynamics method. Dipoles of the chain are simulated as two oppositely charged beads, one of which belong

The influence of the counterion size on the conformational behavior of a single polyelectrolyte chain in a dilute solution in low-polar media has been studied by molecular dynamics. Modeling has been performed both for small counterions, which are sm

We present a theoretical approach for calculating the state of stress induced by a uniform magnetic field in confined magnetoactive elastomers of arbitrary shape. The theory explicitly includes the magnetic field generated by magnetizable spherical i

The possibility of preparing magnetic particles with the “core–shell” structure was demonstrated. The procedure is based on the treatment of carbonyl iron particles with polydimethylsiloxanes (PDMS) containing terminal or distributed over the c

Surface relief of magnetoactive elastomers (MAEs) based on soft polymer matrices filled with anisometric magnetically hard fillers is studied theoretically in magnetic fields applied perpendicular to the MAE surface. A single-particle 2D cell model d
