Synthesis and Study of Mechanical Properties of Polyelectrolyte Ferrogels Based on Strontium Ferrite Particles

摘要

Ferrogels have been synthesized on the basis of a copolymer matrix of acrylamide and potassium acrylate filled with magnetic particles of strontium ferrite SrFe_(12)O_(19), the distribution of which was set by applying magnetic field of 15 and 420 mT. It has been shown that the degree of swelling of ferrogels decreases with the introduction of particles. It has been shown that the application of a magnetic field forms chain structures in bulk ferrogel, which contribute to an increase in the elastic modulus.
