Abstract
In this work, polymeric composites based on room-temperature vulcanized (RTV) silicon rubber incorporated with different NiCr0.2Fe1.8O4 (NCF) content are prepared. The results indicate the well dispersion of various micron-sized particles of NCF with low agglomerations. The decrease in the density is the most advantage property that allows us to obtain the light magnetic material for industrial applications. It is shown that the rubber occupies the porous and defects between NCF particles. It is found that dielectric constant is enhanced with RTV content and decreases with increasing selected frequency for all samples. The electrical conductivity of composite is enhanced with both RTV content and the heat treatment temperature of composites. The saturation magnetization is strongly dependent on NCF content in RTV matrix.
