Magnetic Hydrogels: Magnetic and Mechanical Measurements

Abstract:

Several species of magntic hydrogels (ferrogels) are prepared, and their magnetic and magnetoelastic properties are examined. Three substance are used as the bases: agarose, polyacrylamide and Pluronic. All the gel matrices are filled with the same nanopowder: iron particles with the mean size about 30 nm. The critical concentrations of the magnetic phase, above which the normal gel networks cease to form, are estimated. The magnetization curves of the samples are measured at different stages of de-swelling, and their elastic properties are tested under a uniform magnetic field. The results indicate field-induced rigidity of magnetic hydrogels
