In this work carbon nanoparticle (CNP) was synthesized by an electrical arc discharge method. The electromagnetic (EM) absorbing coatings with different weight fractions of carbonyl iron (CI), CNPs and epoxy resin were prepared. As the weight fraction of CNPs in the composites increased to 1wt%, the minimum reflection loss reached to -9.7dB at 10.3 GHz with a matching thickness of 1mm. This research work concludes that hybrid EM absorbents, in the form of paints, consisting of nano-sized CNPs and micro-sized CI particles show excellent broad bandwidths of absorption. X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Vector network analyzer (VNA) were used for determining structures, morphology and absorption properties, respectively
