Abstract
In this paper, the dielectric and microwave properties of chloroprene rubber (CR) based composites comprising different amounts of furnace carbon black in the range 0-100 phr have been investigated in the frequency range from 1 to 12 GHz. In the frequency range from 1 to 8 GHz the values of the dielectric permittivity and dielectric loss angle tangent are relatively low and do not change significantly with the increase of frequency. In the range from 8 to 12 GHz, the increase in frequency leads to increasing values of relative dielectric permittivity and dielectric loss angle tangent. Increasing the amount of carbon black leads to improved microwave properties of the investigated composites. The composites based on CR containing 60-100 phr furnace carbon black have very good microwave properties and can be used for the needs of anti-radar camouflage and for electromagnetic shielding.
