As the first author, HIT student LIANG Caiyun from the School of Chemical Engineering and Technology, recently published her research paper SiC–Fe3O4 dielectric–magnetic hybrid nanowires: controllable fabrication, characterization and electromagnetic wave absorption in the Journal of Materials Chemistry A. Associate Professor WANG Zhijiang was corresponding author.
Following rapid development of the electronics industry and wireless communication, a wide range of electronic and telecommunication apparatus emitting electromagnetic (EM) radiation is increasingly employed. EM absorption has become a hot research topic and considerate attention is being devoted to the development of high-performance EM absorptive materials. In the research LIANG produced SiC-Fe3O4 hybrid nanowires using a convenient polyol approach in which SiC nanowires were decorated in situ with monodispersed magnetic Fe3O4 nanoparticles. The coverage density of Fe3O4 on SiC is controlled simply by adjusting the weight ratio of the precursors. As the loading density increases, the magnetic loss similarly increases. The hybrids offer a much improved capability for EM absorption than untreated SiC nanowires, within the range 2-18 GHz. The research’s novelty and significance were fully affirmed by reviewers and the research paper was soon accepted as the cover article.
