In this work, FeNi nanosheets decorated silicon carbide nanowires (SiC<sub>nws</sub>) hybrids are prepared by a simple in-situ reduction method. Microstructural studies show that FeNi nanosheets are uniformly distributed on the surface of SiC<sub>nws</sub>, with some other incompact spherical FeNi nanoparticles dissociating out of SiC<sub>nws</sub>. Benefiting from multidimensional heterostructures and the synergistic effect of multiple loss mechanisms, the SiC<sub>nws</sub>@FeNi hybrids exhibit enhanced EM absorption performance compared to pure SiC<sub>nws</sub>. It is worth noting that the excessive introduction of magnetic FeNi leads to a degeneration of EM absorption in the SiC <sub>nws</sub>@FeNi-0.6 sample due to the decline of attenuation capability and impedance mismatch. As a result, the SiC<sub>nws</sub>@FeNi-0.4 sample exhibits the best EM absorption with an effective absorption bandwidth (EAB) of 5.4 GHz at only 1.7 mm, and the minimum reflection loss reaches up to − 50.76 dB at 2.8 mm.

The obtained results indicated that the PMMA-PEG absorbance increased of 69.6% and the transmittance decreased of 46% when the SnO<sub>2</sub>/SiC NPs ratio rise to 4.8 wt%. The PMMA-PEG’s energy gap (<i>E</i><sub>g</sub>) decreased to 3.95 eV when the SnO<sub>2</sub>/SiC NPs ratio reached of 4.8 wt%. The optical constants (coefficient of absorption (<i>α</i>), index of refractive (<i>n</i>), coefficient of extinction (<i>k</i>), real (<i>ε</i><sub>1</sub>) and imaginary (<i>ε</i><sub>2</sub>) parts of dielectric constants, and conductivity of optical (<i>σ</i><sub>op</sub>) were increased of 69.6%, 22.1%, 69.6%, 39.4%, 76.3, and 76.3%, respectively, when SnO<sub>2</sub>/SiC NPs reached of 4.8 wt% at wavelength (<i>λ</i> = 540 nm). These results make the PMMA-PEG-SnO<sub>2</sub>-SiC nanostructures are appropriate for optical and electronic applications. Finally, the gamma radiation attenuation coefficients were increased with rising nanoparticles concentrations. The (PMMA-PEG-SnO<sub>2</sub>-SiC) nanostructures have highest attenuation coefficients for gamma radiation.</p></div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"35 31","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142565802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
