PINTO, Simone de S. and REZENDE, Mirabel C.. Application of poly(o-methoxyaniline) and its carbon black composites in microwave absorbers. Polímeros [online]. 2012, vol.22, n.4, pp.325-331. Epub Aug 14, 2012. ISSN 0104-1428. http://dx.doi.org/10.1590/S0104-14282012005000049.
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.
