Abstract
Electronic devices and communication systems are highly susceptible to interference from unwanted electromagnetic waves. High-performance electromagnetic interference (EMI) shielding offers a solution to this issue. In this work, we discuss the design of an EMI shielding material composite using natural rubber (NR) filled with polyaniline (PANI), multi-walled carbon nanotubes (MWCNT), and ferric oxide (Fe2O3). Different properties of the material composite are studied using scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy. We tested the EMI shielding efficiency of the developed material in the X band and the Ku band. The measurements revealed improved shielding effectiveness when compared to similar microwave shielding materials. In terms of flexibility and cost-effectiveness, this novel composite also proved to be a better alternative.
电子设备和通信系统极易受到有害电磁波的干扰。高性能电磁干扰(EMI)屏蔽为这一问题提供了解决方案。在这项工作中,我们讨论了使用天然橡胶(NR)填充聚苯胺(PANI)、多壁碳纳米管(MWCNT)和氧化铁(Fe2O3)的 EMI 屏蔽材料复合材料的设计。我们使用扫描电子显微镜(SEM)、X 射线衍射(XRD)和傅立叶变换红外光谱(FTIR)研究了复合材料的不同特性。我们测试了所开发材料在 X 波段和 Ku 波段的电磁干扰屏蔽效率。测量结果表明,与同类微波屏蔽材料相比,该材料的屏蔽效果有所提高。在灵活性和成本效益方面,这种新型复合材料也被证明是一种更好的替代品。
期刊介绍:
The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications.
Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field.
A journal of The Minerals, Metals & Materials Society.
