Abstract

We report investigations results obtained from small angle neutron scattering on magnetic elastomers polymerised with and without magnetic field at 25%, 50% and 75% mass concentration of Fe particles with a mean radius of 2.09 µm inside a polymer matrix of stomaflex creme. The magnetic field used in polymerisation process is 156.5 mT. The profiles of the curves have a similar behavior for each concentration, showing that for these sizes of particles and polymerisation process at 156.5 mT, the microstructure of magnetic elastomers is the same in the q-range of 0.006 – 0.1 A-1, and scattering intensities increase proportionally with increasing the mass-concentration of Fe particles.
