“…However other applications exist, linked to the thermal-electric performance and the heat generation of these fabrics. As shown in [58], the measured thermal-electric Seebeck effect is comparable with that of metallic thermocouples. Since polypyrrole shows an extremely low thermal diffusivity regardless of its electrical conductivity, the low thermal conductivity gives significant advantage to the thermoelectric figure-of-merit ZT, comparable with that of some traditional inorganic thermoelectric materials.…”

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.

Electroluminescence (EL) is the property of a semiconductor material pertaining to emitting light in response to an electrical current or a strong electric field. The purpose of this paper is to develop a flexible and lightweight EL device. Thermogravimetric analysis (TGA) was conducted to observe the thermal degradation behavior of NinjaFlex. Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonic acid)-PEDOT:PSS-with ethylene glycol (EG) was coated onto polyester fabric where NinjaFlex was placed onto the coated fabric using three-dimensional (3D) printing and phosphor paste, and BendLay filaments were subsequently coated via 3D printing. Adhesion strength and flexibility of the 3D-printed NinjaFlex on textile fabrics were investigated. The TGA results of the NinjaFlex depict no weight loss up to 150°C and that the NinjaFlex was highly conductive with a surface resistance value of 8.5 ohms/sq.; the coated fabric exhibited a uniform surface appearance as measured and observed by using four-probe measurements and scanning electron microscopy, respectively, at 60% PEDOT:PSS. The results of the adhesion test showed that peel strengths of 4160 N/m and 3840 N/m were recorded for polyester and cotton specimens, respectively. No weight loss was recorded following three washing cycles of NinjaFlex. The bending lengths were increased by only a factor of 0.082 and 0.577 for polyester and cotton samples at 0.1-mm thickness, respectively; this remains sufficiently flexible to be integrated into textiles. The prototype device emitted light with a 12-V alternating current power supply.

“…6 High electrical conductivity, simple polymerization process, low processing cost, and environmental stability constitute the main merits of conductive polymer-coated textiles. [7][8][9] Conducting polymers such as polyaniline, polythiophene, and polypyrrole (PPy) have attracted wide attention because of their electrical and magnetic properties, flexibility, and processability. 10 Among the above-mentioned conducting polymers, PPy is seemingly a promising conducting material especially for thermal and electrical applications.…”

This article verifies the hysteresis phenomenon in heat-voltage curves of polypyrrole-coated electrospun nanofibrous and regular fibrous mats. A thirdorder polynomial model fits the heat-voltage data better than a second-order polynomial model. It was also observed that the hysteresis loop area of nanofibrous and regular fibrous mats increases with decreasing fiber diameter. Moreover, the curvature of the hysteresis loops is significantly affected by the fiber diameter. In fact, the slope of the curvatures increases with decreasing fiber diameter.
