Polyaniline-Co0.5Zn0.5La0.1Fe1.90O4 Composites in the 8.2-12.4GHz Frequency Range

摘要：

The polyaniline(PANI) and PANI-Co0.5Zn0.5La0.1Fe1.9004 (x wt％, x=10,20 and 30) composites were prepared by an in situ polymerization in an aqueous solution. The structure and morphologies of the synthesized products were characterized by Ultraviolet-visible spectrometer (UV-vis), X-ray diffraction (XRD) and Scanning electron microscope (SEM). The complex permittivity(ε”-jε”) and complex permeability (μ”-jμ”) were measured in X-band (8.2-12.4GHz) by using vector network analyzer (HB8510B). The dielectric loss(ε”) of PANI-Co0.5Zn0.5La0.1Fe1.90O4 (x wt％) were lower than those of pure PANI, whereas the magnetic loss(u”) of PANI-Co0.5Zn0.5La0.1Fe1.90O4 (x wt％) were higher than those of pure PANI. Furthermore, the e” values of composites decreased and the u” values of composites increased, respectively, with the increase of Co0.5Zn0.5La0.1Fe1.90O4 relative content.
