The development of radar absorbing materials is a well-researched area with applications in electronics and stealth technology. In this work, two-phase and three-phase systems were produced in which a nano-conducting and magnetic charge were embedded in an insulating polymer matrix. Nickel spinel ferrite was synthesizes using a wet chemical route with a magnetic character, while the graphene nano-filler is a conductive part, both were built into an insulating polymer matrix. Various concentrations were produced for the two-phase system (PVDF polyvinylidene fluoride/graphene) and a selected nano- filler concentration, spinel ferrite, which was incorporated by upto 30% of the weight. These two-phase and three-phase hybrid systems were fabricated using the solution casting route and exemplified using Wide Angle X-ray Diffraction (WAXD), Scanning Electron Microscope (SEM), Impedance Analyzer, Final Tensile Tester (IAFTT) and Network Analyzer Vector (VNA). A summary is presented with recommendations for setting up instruments related to the laboratory.
