摘要
Abstract
The composite material of cenosphere/barium ferrite/polyaniline was successfully prepared by sol-gel self-propagating combustion method combining in-situ doping polymerization deposition technique. The morphology, crystal structure and composition of the samples were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). In addition, the electromagnetic parameters were determined by vector network analyzer in the frequency range of 2-18 GHz. The results show that the maximum dielectric loss and magnetic loss of the prepared sample are 0.30 and 0.52, respectively. Meanwhile, the maximum reflection loss of the prepared sample reaches -33.74 dB at 7.1 GHz, and the absorption bandwidth is 3.2 GHz at -20 dB when the thickness of absorption layer of the prepared sample is 3.0 mm.关键词
