“…This decreasing of capacitance at higher current rates is due to less ionic penetration in the PPy material electrodes compared to the lower current rate, which is a typical behavior of electrochemical supercapacitors. Figure 10c presents the comparison of the energy and power densities between our results and previous reported work on PPy-based textile supercapacitors [34,36,89]. The power density obtained for the as-prepared PPy-based supercapacitors was independent of the PPy polymerization temperature and it retained ca.…”

“…To date, it is still challenging to fabricate PPy in form of well-defined and high conductive layers, especially when it is deposited on textile substrates for textronics products. In the field of smart textiles, PPy layers have shown impressive results for example in textile supercapacitors [34][35][36][37][38] where the specific capacitances ranging from 103 F/g to 325 F/g were reported, such as textile actuators [39,40]; textile heaters [41][42][43]; textile gas sensors [44], where the sensing of PPy finished textiles to NH 3 and HCl gases was indicated; and textile strain sensors [45][46][47], where the possibility of measure the strain in the range of 20-50% was reported. In case of PPy based textile strain sensors, the possibility of measure the strain in the range of 20-50% means, that the measured values of PPy layer resistance are repeatable for the maximum strain, which can be from 20 to 50% dependence on reported solution.…”

“…In the second approach (the most commonly used) the material electrodes are applied to the surfaces of two fabrics and then joined with a solid electrolyte through a separator [34,35,37,38,[58][59][60][61][62][63][64][65][66][67][68][69][70][71]. In reported textile-based supercapacitors such materials like PPy [34][35][36][37][38], reduced graphene oxide (RGO) [56][57][58][59][60][61][62], graphene-based composites with PPy [63,71], PANI [64,65], carbon nanotubes (CNT) [66,67], MnO 2 [68,69], and WO 3 [70] particles were regarded as materials of supercapacitor active electrodes.

Inkjet Printing of Polypyrrole Electroconductive Layers Based on Direct Inks Freezing and Their Use in Textile Solid-State Supercapacitors

In this work, we propose a novel method for the preparation of polypyrrole (PPy) layers on textile fabrics using a reactive inkjet printing technique with direct freezing of inks under varying temperature up to −16 °C. It was found that the surface resistance of PPy layers on polypropylene (PP) fabric, used as a standard support, linearly decreased from 6335 Ω/sq. to 792 Ω/sq. with the decrease of polymerization temperature from 23 °C to 0 °C. The lowest surface resistance (584 Ω/sq.) of PPy layer was obtained at −12 °C. The spectroscopic studies showed that the degree of the PPy oxidation as well as its conformation is practically independent of the polymerization temperature. Thus, observed tendences in electrical conductivity were assigned to change in PPy layer morphology, as it is significantly influenced by the reaction temperature: the lower the polymerization temperature the smoother the surface of PPy layer. The as-coated PPy layers on PP textile substrates were further assembled as the electrodes in symmetric all-solid-state supercapacitor devices to access their electrochemical performance. The electrochemical results demonstrate that the symmetric supercapacitor device made with the PPy prepared at −12 °C, showed the highest specific capacitance of 72.3 F/g at a current density of 0.6 A/g, and delivers an energy density of 6.12 Wh/kg with a corresponding power density of 139 W/kg.

Electronic textiles (e-textiles) have drawn significant attention from the scientific and engineering community as lightweight and comfortable next-generation wearable devices due to their ability to interface with the human body, and continuously monitor, collect, and communicate various physiological parameters. However, one of the major challenges for the commercialization and further growth of e-textiles is the lack of compatible power supply units. Thin and flexible supercapacitors (SCs), among various energy storage systems, are gaining consideration due to their salient features including excellent lifetime, lightweight, and high-power density. Textile-based SCs are thus an exciting energy storage solution to power smart gadgets integrated into clothing. Here, materials, fabrications, and characterization strategies for textile-based SCs are reviewed. The recent progress of textile-based SCs is then summarized in terms of their electrochemical performances, followed by the discussion on key parameters for their wearable electronics applications, including washability, flexibility, and scalability. Finally, the perspectives on their research and technological prospects to facilitate an essential step towards moving from laboratory-based flexible and wearable SCs to industrial-scale mass production are presented. IntroductionWearable electronic textiles (e-textiles) have been going through significant evolutions in recent years, due to the continuous progress of material science and nanotechnology, miniaturization, and wireless revolution. [1,2] E-textiles possess functionalities such as sensing, computation, display, and communication, [3][4][5][6]
