“…The methods used to incorporate conductive materials with the fibres or yarns needs sophisticated processes and/or equipment which compromises large scale production. In contrast, process complications can be reduced considerably by incorporating conductive materials directly onto preformed textiles fabrics using polymerisation, deposition of metals, weaving or integration of metal fibres or wires [1,13,[15][16][17][18][19][20][21].…”

A cost effective electrically conductive textile for large scale applications would revolutionise numerous industries. Herein, we demonstrate a novel processing approach to produce conductive textiles for industrial applications. A conductive nonwoven textile was successfully fabricated using a simple dip coating method. The nonwoven polyester was coated with liquid crystallite graphene oxide with subsequent non-toxic chemical reduction. The process is readily scalable. The graphene coated fabric has been characterized by electron microscopy as well as by electrical, mechanical, thermal and abrasion resistance measurements. It was found that the electrical surface resistivity of the prepared polyester-graphene composite fabric was 330 Ω □-1. The electrical surface resistivity was 3 and 150 times lower than that of polypyrrole coated woven polyester fabric and graphene coated nonwoven fabrics, respectively, in previously published reports. The hybrid polyester-graphene textile prepared here should find applications in high-performance geotextiles or as heating elements.

“…Unlike metals, their conductivity can be tailored by varying the level and kinds of doping [1]. But they lack processability to form fibres or filaments due to their inherent structural intractability and stiffness that comes from conjugation along molecular chain [2,3]. Among these conductive polymers, polypyrrole (PPy) has low cost, good environmental stability, and satisfactory electrical conductivity in doped condition [4][5][6][7].…”

Electrically conductive woven, knitted, and nonwoven composite fabrics are prepared by in situ chemical polymerization of pyrrole using suitable oxidant and dopant. These composite fabrics show surface resistivity in the range ∼1 to 2 kΩ. These composite fabric can alter their resistivity with various stimuli such as mechanical strain, pH, and humidity. So, in the present study, their response to pH, humidity, and mechanical strain is investigated. For all fabrics, similar behaviour has been observed regarding pH versus resistivity. The resistance of the composite fabric increases with the increase of alkalinity of pH. However, as bending strain increases, resistance steeply decreases for cotton fabrics, steeply increases for polyester fabrics, and initially decreases and then increases for wool fabrics. Regarding humidity sensitivity, sigmoid curves have been obtained for all kinds of fabrics.

“…Also in [59], the researchers worked for the preparation and characterization of electrically conductive polyester textiles for heat generation. They used needle-punched nonwoven, spunlace nonwoven, and woven fabrics, which had been made electrically conductive by in situ chemical polymerization of pyrrole with p-toluene sulfonic acid dopant.…”

Abstract:The polypyrrole, in its intrinsically conducting form, can be used to prepare composites such as polypyrrole/polyester textiles by coating yarns or fabrics made of polyester. In this manner, we obtain textiles that can be involved in several applications, among which we find the use of textiles in electromagnetic shielding. However, several other uses of polypyrrole/polyester composites are possible, such as in biomedical applications. Here we propose a survey of the literature about these composites. Keywords: Textiles, Polypyrrole, Intrinsically Conducting Polymers, Electromagnetic shielding IntroductionWhen opportunely processed, the polypyrrole becomes an intrinsically conducting polymer. This material can be used to prepare polypyrrole/polyester textile composites, by coating yarns or fabrics made of polyester. In this manner we obtain textiles that can be used for several applications. Two of them are the electromagnetic interference (EMI) shielding and the radiation-absorbent camouflage [1][2][3][4][5]. Materials for EMI shielding are needed due to the interference of radio frequency and microwave devices with computers, transformers, cables, mobile phones, medical devices, and also for the effect of the radiation on human health. Applications of textiles is therefore required for the shielding of persons, devices or large volumes such as those of an entire room. In the case that textiles are applied as radiation-absorbent materials they can be used in stealth technology, to disguise devices or structures from radar detection. Other applications of the polypyrrole/polyester fibres and fabrics are possible, in particular in the biomedical area.
