摘要: In this communication, novel hexanoic acid (HA) doped PAni micro/nanocomposites containing TiO2 (dielectric filler, 30 nm) and Fe3O4 (magnetic 1 µm) that possess high conductivity, dielectric, magnetic properties are reported. The were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), ultraviolet (UV) spectrophotometer, thermogravimetric analysis (TGA), scanning electron microscopy (SEM) analyses. magnetic, microwave absorption of the discussed. resultant nanorods/tubes shown in SEM images indicate exhibit polymerization through elongation. results show synthesis parameters such as amount particle size used significantly affect morphology, property PAni. PAni/HA/TiO2/Fe3O4 with 40% achieves best performance (greater than 99.4% absorption) at frequency suitable to be applied a good absorbing shielding material. Copyright © 2009 John Wiley & Sons, Ltd.
