TEXTILES FOR ELECTROMAGNETIC RADIATION SHIELDING

Abstract

Analysis  of  existing  textile  materials  used  for  electromagnetic  radiation  shielding,  their systematization, and basic production methods are the main goals of this review. Methodology. The review of scientific literature and the systematization of the results in the field "textile materials for electromagnetic interference" are the main methods used for this research. Shielding  materials  based  on  textile  materials  are  widely  used  for  protection  against electromagnetic  radiation  (EMR)  from  existing  electrical  and  electronic  devices.  Methods  for  imparting shielding properties to textile materials can be classified in two directions: surface treatment and fillers. The solutions  used  to  add  conductivity  to  textiles  are  very  diverse  and  depend  on  the  shield  application. However, surface treatment is often time consuming and expensive. The introduction of fillers in the form of particles,  fibers,  threads  and  fabrics  into  the  material  are  increasingly  using  to  create  electromagnetic
shields. Textile shielding materials are made from conductive polymers, metal fibers (carbon, stainless steel, copper, etc.), metal wires, metal-coated threads or multifilaments. Generally, the electrical conductivity and shielding efficiency from EMI of all textile materials (woven, knitted, non-woven fabrics) are improved by
incorporating metal fibers, metal particles or conductive polymers into them at different production stages. Scientific novelty. The detailed analysis of textile materials for shielding against electromagnetic radiation  and  of  the  research  works  in  this  field  are  presented  in  this  review.  The  existing  methods  for
producing textile shields are systematized by the authors. Practical value. It is a familiarization of a wide circle of specialists with the current state of the problem of protection against electromagnetic radiation. The main trends and prospects for the development of textile materials for electromagnetic shielding are identified as a result of this review.
