Estudo da aplica?§?￡o da poli(o-metoxianilina) e de seus comp?3sitos com negro de fumo no processamento de absorvedores de micro-ondas

摘要

This study deals with the production of radar absorbing materials (RAM) based on poly(o-methoxyaniline) (POMA) and its conductive composites with carbon black (CB) (CB/POMA). The electrical conductivity of the CB/POMA composite was significantly higher (0.23-80 S.cm-1) than for POMA (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.
