Dielectric Spectroscopy of Hybrid Magnetoactive Elastomers [PDF]

open access: yesPolymers, 2021
Dielectric properties of two series of magnetoactive elastomers (MAEs) based on a soft silicone matrix containing 35 vol% of magnetic particles were studied experimentally in a wide temperature range. In the first series, a hybrid filler representing a mixture of magnetically hard NdFeB particles of irregular shape and an average size of 50 μm and ...
