Abstract

Results of synthesized polyaniline (PANi) prepared by a continuous polymerization process is reported. The purpose of this research is to obtain material absorber which maximum absorption. FTIR spectrum for synthesized PANi showed no double bond absorption peak at 3442 cm-1 which indicates the polymer chain was formed through repetition of single bonds. The results of the electrical conductivity measurement showed the value 17.5 μS/cm for synthesized PANI. The value increased dramatically to 3600, 1520 and 920 μS/cm after the addition of photonic acids of HClO4, H2SO4 and HCl respectively. Those values were obtained through sequences process. Results of particle size distribution confirmed that all synthesized PANi have nanoparticles. In addition, all synthesized PANi have shown electromagnetic wave absorbing properties in the frequency range 12-18 GHz. The best peak Reflection Loss (RL) values -10 dB (∼ 68 % absorption) and -25 dB (∼ 84 %) at 13 and 16.5 GHz respectively obtained on the PANi Emeraldine base (PANi-EB).
