چکیده انگلیسی
Core-shell ternary composite composed of a Sn/SnO2 nanoparticle core and amorphous carbon shell were successfully prepared by a simple hydrothermal route. Crystal phase structure, composition, morphology of the final product were characterized by the transmission electron microcopy, X-ray photoelectron (XPS) and Raman technique. This ternary composite presented excellent electromagnetic absorption properties if applied to treat the electromagnetic interference issue (EMI). The optimal effective absorption frequency covered 6.8Â GHz with a thin coating thickness, which was quite better than Sn@C and SnO2@C binary composite. The improvement electromagnetic absorption mechanism was attributed to the moderate permittivity value which ensure the balanced impedance matching and dielectric loss ability. Besides, the probably interface polarization effect was proposed in this research which benefited to the attenuate electromagnetic wave.
