  • magnetic fe nanoparticle to decorate n dotted c as an exceptionally absorption dominate Electromagnetic Shielding Material
    Composites Part B-engineering, 2020
    Co-Authors: Zirui Jia, Ailing Feng, Chuanhui Zhang, Xuehua Liu, Kaichang Kou, Shuai Yin, Haijie Cao
    Abstract:

    Abstract Conversional Electromagnetic Shielding Material with strong reflection coefficient are becoming insufficient for today's application, since the serious 2nd Electromagnetic pollution. Herein, we demonstrate a magnetic carbon based Shielding Material constructed by magnetic Fe nanoparticles (NPs) and N dotted amorphous carbon nanosphere (~200 nm). The structure, morphology, chemical composition of the samples have been studied in depth. It is observed that the average sizes of Fe NPs is ~8.0 nm and can be loaded well on the surface of N dotted amorphous spheres. The Electromagnetic Shielding performance has been investigated. Significantly, the as-prepared samples show excellent Electromagnetic Shielding performance. The maximum Shielding effectiveness can up to 30 dB under a thickness of 1.2 mm. More importantly, the reflection coefficient can be reduced to 2.3 dB, presenting excellent absorptiondominate Shielding performance. The desirable Shielding mechanism with less reflection are attributed to the boosted loss ability and matched impedance matching behavior, which originate from N doping and magnetic component. This work which integrates magnetic component with N dotted amorphous carbon has been demonstrated as a useful strategy for the development of absorption dominate EM Shielding Material.

  • a low dielectric decoration strategy to achieve absorption dominated Electromagnetic Shielding Material
    Composites Part B-engineering, 2020
    Co-Authors: Zirui Jia, Chao Wang, Ailing Feng, Pengbao Shi, Chuanhui Zhang, Xuehua Liu, Kuikui Wang
    Abstract:

    Abstract The Shielding mechanism for conversional Electromagnetic Shielding Material is mainly dependent on the reflection, thus the Electromagnetic interference (EMI) or pollution can't be really solved, owing to the 2nd interference or pollution. To overcome this barrier, we developed an absorption dominate EMI Shielding Material, using low permittivity component (TiO2, amorphous carbon and SiO2) to decorate magnetic carbonyl iron (CIF). Consequently, the impedance matching ability can be greatly improved, simultaneously showing desirable dual magnetic and dielectric loss ability. The varied morphology, crystal phases and EMI Shielding performance of resultants have been well studied. It has been confirmed that the reflection coefficient of SiO2 decorated CIF sample could be reduced from 90 to 56.6%, suggesting the improved EM absorption ability. Meanwhile, it corresponding absorption coefficient could up to 43.3%, which is also much better than TiO2 or amorphous decorated CIF. The method for the successfully use low-dielectric component to decorate magnetic metal has been demonstrated as a useful strategy for the preparation of achieving absorption dominate EM Shielding Material.
