Microwave-absorbing and mechanical properties of carbonyl-iron/epoxy-silicone resin coatings

Coatings with flake carbonyl-iron particles as absorber and epoxy-silicone resins as matrix were prepared. The complex permittivity, complex permeability and microwave-absorbing properties were investigated in the frequency range of 2–18 GHz. Both the real part of permittivity and permeability were increased with carbonyl-iron weight concentration. The minimum reflection loss shifts to the low-frequency region with increase in carbonyl-iron...
