Abstract This work outlines the efforts to qualify a few wearable fabrics electrodeposited with nickel, as efficient absorbents of microwaves in X band. Here two samples of fabrics — a natural fiber based linen and an artificial fiber based nylon fabrics were chosen for electrodeposition. The surface activation of the fabric was carried out through sputtering of platinum, followed by electrodeposition of nickel using Watts bath solution. Interestingly, the two step process has transformed the fabric from an electromagnetic (EM) transparent material to an excellent electromagnetic interference (EMI) attenuator, retaining its flexibility and breathability. Microstructural analysis of electrodeposited fabrics showed much thicker and broader Ni deposits for linen than nylon fabric due to the availability of more bundle of fibers. Further, the abundance of lint in linen provide more surface to deposit Ni, which helps in achieving better shielding values. Metallic and ferromagnetic characteristics of the Ni deposited fabric structures were investigated. Exceptional EMI shielding efficiency of 45–52 dB is achieved for Ni deposited linen, which means 99.999% of attenuation is attained. The outcome of this research can lead to the development of lightweight, wearable and flexible ‘radar invisible fabrics’, which has wide range of applicability in defense and healthcare sectors.

镍电沉积纺织品作为可穿戴雷达隐形织物

摘要 这项工作概述了将几种电沉积镍的可穿戴织物鉴定为 X 波段微波的有效吸收剂的努力。这里选择了两种织物样品——一种基于天然纤维的亚麻布和一种基于人造纤维的尼龙织物，用于电沉积。织物的表面活化通过铂的溅射进行，然后使用瓦特浴液电沉积镍。有趣的是，两步工艺将织物从电磁 (EM) 透明材料转变为出色的电磁干扰 (EMI) 衰减器，保持其柔韧性和透气性。电沉积织物的微观结构分析表明，由于可以获得更多的纤维束，亚麻织物的镍沉积物比尼龙织物更厚更广。更多，亚麻布中大量的棉绒提供了更多的表面来沉积镍，这有助于实现更好的屏蔽值。研究了镍沉积织物结构的金属和铁磁特性。Ni 沉积亚麻布实现了 45–52 dB 的卓越 EMI 屏蔽效率，这意味着实现了 99.999% 的衰减。这项研究的成果可以开发出轻质、可穿戴和灵活的“雷达隐形面料”，在国防和医疗保健领域具有广泛的适用性。达到 999% 的衰减。这项研究的成果可以开发出轻质、可穿戴和灵活的“雷达隐形面料”，在国防和医疗保健领域具有广泛的适用性。达到 999% 的衰减。这项研究的成果可以开发出轻质、可穿戴和灵活的“雷达隐形面料”，在国防和医疗保健领域具有广泛的适用性。
