Reduced graphene oxide (rGO) with diverse, layered structures and unique electronic characteristics was restricted in microwave wave absorption owing to the high dielectric easy agglomeration properties. In situ, polymerization method is adopted prepare rGO@PANI codoped Mn2O3 CoFe2O4 composites as an efficient absorber. The resultant material thoroughly characterized for phase morphological analysis magnetic parameters, which revealed that particles dispersed across composite. Our finding shows at 35 wt % loading, sample PGF 1 EAB of 5.07 GHz a maximum reflection loss (RLmax) −22.79 dB 2 mm thickness; 2, achieved RLmax −48.44 2.3 thickness 3.6 EAB, while 3 exhibits 2.64 −47.03 7.28 3.4 mm. notable differences conduction electrons structure between decorated outer layers significantly enhance interfacial polarization. By creating quicker electron transport routes, 3D hierarchical network topology further improves outcomes. well-thought-out planning cooperative action sheets are intimately connected polarization, results incredibly lightweight thin suitable field RADAR absorption. Remarkably, 40 loading microwaves entire X Ku bands only 2.4 covers 92.5% whole frequency region (2–18 GHz) up 6
