摘要:The rise of modern communication devices has seriously imperiled human health due to electromagnetic (EM) pollution. In this context, the aim of this work is to develop novel reduced graphene oxide/Co-doped ZnNi ferrite/polyaniline ternary composites that exhibit enhanced microwave absorption properties. It is observed that the ternary composite prepared by in-situ polymerization show best EM absorption. The maximum reflection loss (R-L ) reaches -24.2 dB and the efficient bandwidth (R-L < -10 dB) is more than 3 GHz with an absorbed thickness of 1.7 mm. The in-depth analysis based on complex permittivity and permeability reveals that the improved microwave absorption ability is related to the uniform sandwich-like multilayer structure and impedance compatibility of the ternary composites. The results and analysis show that these ternary composites with small thickness and wide absorption band are the potential candidates for microwave absorption applications. (C) 2018 Elsevier B.V.
