In this study, we mixed camouflage paint with the reducing particles, and then measured the corresponding electromagnetic wave absorbing properties. The supplementary of radar absorbing function for camouflage paint is the main purpose of this study. The camouflage paint used were obtained from Chemical system research division of the CHUNG-SHAN institute of science. The hybrid paints were prepared with the addition of various magnetic nanopowders, electric conductivity powders and dielectric powders. The paints then blushed on the metal aluminum plates with different thickness of coating. The frequency response range of 3-18GHz were examined on the respects of the adding amount of powder. From the experimental results, we have demonstrated that the addition amount of particles determined the matching condtion for electronmagnetic wave absorbing. In this study, the absorbing powders of graphite with the addition amount of less thant 10 wt% show the efficient absorbing effect. with the advantage of light weight of graphite, it is helpful to develop lighter and thinner coating of radar absorbing paints.
