摘要：

The (BaFe12O19+BaTiO3)/polyaniline composite was synthesized by in situ polymerization and introduced into epoxy resin and polyethylene to be a microwave and infrared absorber. The spectroscopic characterizations of the formation processes of (BaFe12O19+BaTiO3)/polyaniline composite were examined using Fourier transform infrared, ultraviolet-visible spectrophotometer, X-ray diffraction, scanning electron microscopy, transmission electron microscopy and electron spin resonance. Microwave absorbing properties were investigated by measuring reflection loss in 2-18 and 18-40 GHz microwave frequency range using the freespace method. Thermal extinction measurements in the 3-5 and 8-12 mu m were done to evaluate the shielding effectivity of infrared. The results showed that a significant absorption frequency range shifting and thermal extinction could be obtained by adding polyaniline to the BaFe12O19+BaTiO3 blend. (C) 2010 Elsevier B.V.
