摘要
Conductive elastomer blends of ethylene-propylene-diene rubber, EPDM, and polyaniline, PAni, doped with dodecylbenzene sulfonic acid, DBSA, were prepared and evaluated as a radar absorbing material, RAM. Reflectivity measurements in the 8-12 GHz frequency range, using the NRL arch method, were done to evaluate the shielding effectivity. The results showed that the dopant and PAni concentrations and also the sample thickness affect these measurements. Good shielding values were obtained (similar to 15 dB) with the 50/50, 40/60 and 20/80 (w/w %) EPDM/PAni blends.
