MAGNETICALLY ACTIVE ELASTOMER Russian patent published in 2023 - IPC H01F1/28 H01F1/113 H01F1/117 

FIELD: electrical engineering.

SUBSTANCE: composite magnetically active materials, specifically magnetically active elastomers that reversibly change their physical characteristics under the influence of a magnetic and electric field, used in mechanical engineering, electrical engineering, instrumentation, medicine. The selected quantitative content of carbon nanotubes and fullerenes in the composition of the elastomer provides an exponential increase in the dielectric constant, which improves the magnetorheological properties of the final material.

EFFECT: obtaining a material with enhanced magnetically controlled properties and improved elastic strength characteristics, which is provided due to the fact that fillers based on fullerenes and carbon nanotubes are additionally introduced into the magnetically active elastomer based on iron particles in the following ratio of components in wt.%: iron powder, obtained by spraying, 50.0-70.0, synthetic rubber 20.0-45.0, cross-linking agent 2.0-3.0, fullerenes 2.5-3.0, carbon nanotubes 0.7-0.7.
