This research shows the processing and design of radar absorbing material (RAM) based on barium hexaferrite (BaM) and poly(aniline, pyrrole, ethylene terephthalate) (PAni,PPy,PET). BaM was prepared by sol gel method with Ni-Zn doping at mole fraction of 0. 4 to obtain soft magnetic material. BaM/(PAni,PPy) composites were synthesized by in-situ polymerization method at ∼0 °C. (BaM/PET) composite was prepared by melt compounding at 220°C. The composites were coated on A-grade AH36 steel using Dallenbach Layer, Salisbury Screen and Jaumann Layer methods with thickness of 2, 4, and 6 mm. The composites were evaluated using XRD, SEM, FTIR, VSM, LCM-meter and VNA. Results showed that doped BaM showed BaNixZnxFe12-2xO19 structure. BaM/(PAni,PPy,PET) composites possessed globular morphology with M-O and C-H bonds. BaNixZnxFe12-2xO19 exhibited the value of Ms and Hc, 56.6 emu/g and 60 Oe respectively. High electrical conductivity of 1.77744 × 10-5 S/cm was achieved of BaM/PAni composite. The maximum reflection loss (RL) was reached at - 48.720 dB and 8.1 GHz for BaM/PAni composite coating with 6 mm thickness at Jaumann Layer. These results indicated that BaM/PAni composite was a soft magnetic material with a high RL value that is suitable for RAM, which used in stealth technology on naval vessels.
