Abstract

Introduction: The electromagnetic radiation caused by the increasing application of electronic devices is associated with environmental hazards and health risks. background: The electromagnetic radiation caused by the increasing application of electronic devices is associated with environmental hazards and health risks. With the rapid development of science and technology, it is urgent to reduce electromagnetic interference by introducing effective electromagnetic shielding materials. Furthermore, novel electromagnetic shielding materials with increasing stability and decreasing density have become the focus of the current researches. Method: With the rapid development of science and technology, it is urgent to reduce electromagnetic interference by introducing effective electromagnetic shielding materials. Furthermore, novel electromagnetic shielding materials with increasing stability and decreasing density have become the focus of the current research. Herein, silver (Ag) coated rubber (AR) micro-particles (MPs) were prepared by coating Ag nanoparticles (NPs) onto waste AR MPs. objective: Fabrication of Silver (Ag) coated rubber (AR) micro-particles (MPs). Result: The AR MPs not only exhibited superior electromagnetic shielding performance with the electromagnetic interference (EMI) shielding effectiveness (SE) value of 6.1 dB at 5.8 GHz, but also possessed excellent long-time stability (240 h) in high-temperature (85 °C) and high humidity (85% RH) environment. Due to the low density (0.66 g/cm3) of AR-3 MPs, its practical application in lightweight and highly integrated electronic devices is guaranteed. Conclusion: The developed AR MPs have exhibited broad application prospects in the electromagnetic interference (EMI) shielding field due to the good EMI shielding performance, high stability and low density.
具有低密度、高稳定性和优异电磁屏蔽能力的银涂层废橡胶微粒:设计、制备和表征
导言:电子设备的日益广泛应用所产生的电磁辐射与环境危害和健康风险有关:电子设备的应用日益广泛,由此产生的电磁辐射对环境和健康造成危害。随着科学技术的飞速发展,迫切需要引入有效的电磁屏蔽材料来减少电磁干扰。此外,稳定性增强、密度减小的新型电磁屏蔽材料已成为当前研究的重点。研究方法随着科学技术的飞速发展,引入有效的电磁屏蔽材料以降低电磁干扰已迫在眉睫。此外,稳定性更高、密度更小的新型电磁屏蔽材料也成为当前研究的重点。本文通过在废弃的 AR 微颗粒上涂覆银纳米颗粒(NPs),制备了银(Ag)涂层橡胶(AR)微颗粒(MPs):制备银(Ag)包覆橡胶(AR)微颗粒(MPs)。结果:AR MPs 不仅具有优异的电磁屏蔽性能,在 5.8 GHz 频率下的电磁干扰(EMI)屏蔽效能(SE)值为 6.1 dB,而且在高温(85 °C)和高湿度(85% RH)环境下具有出色的长期稳定性(240 h)。由于 AR-3 MPs 的密度较低(0.66 g/cm3),保证了其在轻型和高集成度电子设备中的实际应用。结论所开发的 AR MPs 具有良好的 EMI 屏蔽性能、高稳定性和低密度,在电磁干扰(EMI)屏蔽领域具有广阔的应用前景。
