文摘
In this experiment, excellent microwave absorption properties of Ag/SrFe12O19/NanoG were prepared via a two-step reaction. First, the SrFe12O19 was deposited on the surface of NanoG by sol–gel method. Then, the Ag/SrFe12O19/NanoG was perpared via electroless plating. The obtained ternary composites were analyzed by SEM, XRD, VSM and a vector network analyzer. The results indicated that the NanoG is covered by SrFe12O19 and SrFe12O19/NanoG is completely wrapped by silver layer. Ag/SrFe12O19/NanoG’s conductivity and Ms are 2.2 S/cm and 15.4 emu/g, respectively. Measurement of the vector network analyzer suggests that the microwave absorbing properties of Ag/SrFe12O19/NanoG are better than those of NanoG and SrFe12O19/NanoG. Its maximum reflection loss value can reach −29 dB at 10.9 GHz when the thickness is 2.0 mm, and it’s the best match thickness of the composites in the X band.
