“…By the sputtering method, it is possible to deposit metallic as well as semiconductor and dielectric layers. An additional advantage of the method is the good adhesion of deposited layers to the substrate [145]. Kim et al adopted a direct current magnetron sputtering method to decorate polyimide fabrics with nanofilms of two metals silver and copper one after another.…”

“…Metallization of PP nonwoven textile substrate by zinc magnetron sputtering could act as a shield to attenuate EM waves in the frequency range of 30 –1300 MHz The attenuation level could be realized by obtaining SE value (over 50 dB) with surface resistance in the order of 10 3 Ω. Moreover, the value of SE is influenced by the three-dimensional assembly of the surface [145].…”

The rapid proliferation of electronic devices and their operation at high frequencies has raised the contamination of artificial electromagnetic radiations in the atmosphere to an unprecedented level that is responsible for catastrophe for ecology and electronic devices. Therefore, the lightweight and flexible electromagnetic interference (EMI) shielding materials are of vital importance for controlling the pollution generated by such high-frequency EM radiations for protecting ecology and human health as well as the other nearby devices. In this regard, polymeric textile-based shielding composites have been proved to be the best due to their unique properties such as lightweight, excellent flexibility, low density, ease of processability and ease of handling. Moreover, such composites cover range of applications from everyday use to high-tech applications. Various polymeric textiles such as fibers, yarn, woven, nonwoven, knitted, as well as their hybrid composites have been extensively manipulated physically and/or chemically to act as shielding against such harmful radiations. This review encompasses from basic concept of EMI shielding for beginner to the latest research in polymeric-based textile materials synthesis for experts, covering detailed mechanisms with schematic illustration. The review also covers the gap of materials synthesis and their application on polymeric textiles which could be used for EMI shielding applications. Furthermore, recent research regarding rendering EMI shielding properties at various stages of polymeric textile development is provided for readers with critical analysis. Lastly, the applications along with environmental compliance have also been presented for better understanding.

“…Одной из востребованных ассортиментных групп являются материалы, экранирующие электромагнитные излучения, обладающие повышенной износостойкостью, воздухо-и паропроницаемостью, что позволяет использовать их для производства защитной одежды [1]. Для получения экранирующих текстильных материалов важным является наличие электропроводящего слоя, способного обеспечить низкое поверхностное сопротивление [2]. Одним из способов получения электропроводящих материалов является нанесение металлических покрытий, при этом для получения электропроводящего слоя металлические покрытия могут наноситься на полимерные пленки, закрепленные на текстильном материале методом термопереноса или с использованием адгезива [3].…”

The article presents the results of a study of the complex properties of metallised textile materials laminated with polymer films by thermal pressing. The application of a copper metal coating to the surface of a textile material was carried out by magnetron sputtering. To increase the adhesion of synthetic textile materials to the metal coating, pretreatment in plasma of a radio-frequency capacitive (RFC) discharge of reduced pressure was used, carried out immediately before spraying the metal within one technological cycle. It has been established that the metallised textile materials obtained have a shielding coefficient of up to 50 dB, and the use of perforated films for lamination makes it possible to obtain materials with air and vapour permeability. The use of plasma modification in the process makes it possible to increase the adhesion of polymer materials to metal coatings, which contributes to an increase in the wear resistance of the resulting textile materials with shielding properties.

“…Metallic films including Zn were deposited on polypropylene nonwoven surfaces in argon atmosphere in order to obtain shielding effect as seen in Figures 3 and 4 [41]. Electromagnetic shielding effect of metallic thin films on the woven fabrics consisting of metal/PET filaments obtained by vacuum evaporation deposition technique was investigated.…”
