This study deals with the production of radar absorbing materials (RAM) based on poly(o-methoxyaniline) (PUMA) and its conductive composites with carbon black (CB) (CB/PUMA). The electrical conductivity of the CB/PUMA composite was significantly higher (0.23-80 S.cm(-1)) than for PUMA (0.017 S.cm(-1)). The attenuation of the electromagnetic radiation in the range between 8 and 12 GHz was highest for CB/POMA-conductive composites in epoxy resin, reaching up to 99.5% at 11.7 GHz.
