Research Progress on Electromagnetic Textile Materials

Abstract
The electromagnetic parameter of common textile materials has not reached the order of magnitude of metals or semiconductors [1]. They generally do not own any electromagnetic function. In the article, the concept of electromagnetic textile material and its basic preparation method are proposed. Finally, the application of electromagnetic textile materials is briefly introduced [2].

Introduction
Common textile materials have dielectric properties and electrostatic phenomena, but the electromagnetic parameter of them has not reached the order of magnitude of metals or semiconductors. The electromagnetic properties of textile materials include electrical conductivity [3], dielectric properties, electrostatic and magnetic properties, etc. Therefore, they generally do not own any electromagnetic function.

With the rapid development of conductive polymer in-situ polymerization technology, metal, metal oxide and fiber material hybrid technology and the metallization processing technology of fiber materials, the conductor preparation technology of textiles has become more and more perfect, forming a series of electromagnetic functional electromagnetic textile materials such as shielding textiles, antistatic textiles, absorbing materials, wearable antennas etc. [4].

Electromagnetic Textile Materials
Electrical conduction is the movement of electrically charged particles through a transmission medium. Conductive property is determined by the type of atoms in a material. Materials in which a large number of electrons can move freely are called conductors, and Materials with low electron mobility are called insulators.

Ordinary fibers are generally made of non-conductive and non-magnetic polymer materials. Electromagnetic textile materials are a new type of functional textile materials obtained from fibers or yarns with good electrical and magnetic properties through textile processing technology or coating conductive material on the common textile material in the finishing process. Meanwhile, electromagnetic textile materials have unique structure of textile materials and the electromagnetic properties of the metal materials [5].
