Journal ArticleDOI
Novel highly elastic magnetic materials for dampers and seals: Part I. Preparation and characterization of the elastic materials
Sergey S. Abramchuk,Elena Yu. Kramarenko,Elena Yu. Kramarenko,Gennady V. Stepanov,L.V. Nikitin,Genovéva Filipcsei,Alexei R. Khokhlov,Alexei R. Khokhlov,Miklós Zrínyi +8 more
TL;DR: In this article, the authors study fundamental principles governing the preparation of magnetic elastomers as well as their structure and elastic properties, and propose a method for determining the behavior of these materials depending on the composition, external conditions, and the synthesis processes.
Journal ArticleDOI
Weakly Charged Polyelectrolytes: Collapse Induced by Extra Ionization
TL;DR: In this paper, it was shown that the collapse transition in weakly charged polyelectrolyte gels or single macromolecules can take place with an increase in the degree of ionization (e.g., during titration of a weak polyacid).
Journal ArticleDOI
Experimental study of the magnetic field enhanced Payne effect in magnetorheological elastomers
Vladislav V. Sorokin,Eva Ecker,Gennady V. Stepanov,Mikhail Shamonin,Gareth J. Monkman,Elena Yu. Kramarenko,Alexei R. Khokhlov +6 more
TL;DR: It is found that the Payne effect significantly increases in the presence of an external magnetic field and varies with the cyclical loading which reaches saturation after several cycles.
Journal ArticleDOI
Hysteresis of the viscoelastic properties and the normal force in magnetically and mechanically soft magnetoactive elastomers: Effects of filler composition, strain amplitude and magnetic field
Vladislav V. Sorokin,Gennady V. Stepanov,Mikhail Shamonin,Gareth J. Monkman,Alexei R. Khokhlov,Elena Yu. Kramarenko +5 more
TL;DR: Hysteresis in dynamic modulus, loss factor and normal forces of magnetoactive elastomers (MAEs) comprising various proportions of small (3-5) and large (50-60) ferromagnetic particles are experimentally studied using dynamic torsion performed at a fixed oscillation frequency in varying DC magnetic fields as discussed by the authors.
Journal ArticleDOI
Polyelectrolyte/Ionomer behavior in polymer gel collapse†
TL;DR: In this paper, the theory of collapse of weakly charged polyelectrolyte gels is generalized by taking into account the possibility of counter ion trapping with the formation of ion pairs, which becomes progressively important as the gel shrinks and the dielectric constant of the gel medium decreases.
