“…Further functionalization to improve its performance was achieved by coating the fibres with polypyrrole (Ppy). In situ polymerization of pyrrole (C 4 H 5 N, Sigma-Aldrich, Mw = 67.09 g.mol −1 , purity = 98%) on the surface of carbon wire was carried out using FeCl 3 .6H 2 O (Sigma Aldrich) as the oxidizing agent according to the protocol reported on previous work 15, 16 . The carbon wires (~ 4 cm long and 180 µm thick) were immersed in an aqueous solution of pyrrole, 0.05 M for 10 min under magnetic stirring.…”

flexible and stretchable energy-storage batteries and supercapacitors suitable for wearable electronics are at the forefront of the emerging field of intelligent textiles. In this context, the work here presented reports on the development of a symmetrical wire-based supercapacitor able to use the wearer's sweat as the electrolyte. the inner and outer electrodes consists of a carbon-based thread functionalized with a conductive polymer (polypyrrole) which improves the electrochemical performances of the supercapacitor. The inner electrode is coated with electrospun cellulose acetate fibres, as the separator, and the outer electrode is twisted around it. the electrochemical performances of carbon-based supercapacitors were analyzed using a simulated sweat solution and displayed a specific capacitance of 2.3 F.g −1 , an energy of 386.5 mWh.kg −1 and a power density of 46.4 kW.kg −1. Moreover, cycle stability and bendability studies were performed. Such energy conversion device has exhibited a stable electrochemical performance under mechanical deformation, over than 1000 cycles, which make it attractive for wearable electronics. finally, four devices were tested by combining two supercapacitors in series with two in parallel demonstrating the ability to power a LeD. Wearable electronic devices have emerged in the last decade due to a remarkable interest in intelligent textiles or electronic skin applications. Transistors, memory devices, organic light emitting diodes, triboelectric and energy storages devices have been produced in flexible substrates enabling conformity to curved surfaces 1. Among the storage devices proposed, the fibre device is the most attractive as it can be incorporated directly on textiles or other wearable applications 2. Therefore, numerous works have focused on the development of fibre-based capacitors and supercapacitors 3-6. These devices can be produced in sheets and rolled out to have a fibre geometry. Kim and co-workers 7 have tested a carbon fibre paper as electrode reaching a specific capacitance of 140 F.g −1 and 90% of capacitance retention after 5000 cycles using 0.5 M H 2 SO 4 as electrolyte and Ag/AgCl as the reference electrode. They have further improved these performances with decorated Polypyrrole-NiCo 2 O 4 carbon paper 8 reporting specific capacitance of 900 F.g −1 (at 1A), and 88% of capacity retention (5 A.g −1) after 10,000 cycles. Silver nanodendritic cellulose acetate electrodes were tested by Kesavan Devarayan 9 in the form of flexible sheets showing specific capacitance in the range of 125 F.g −1 after 1000 cycles and a capacitance retention around 20%. Single-walled carbon nanotube/polyaniline (SWCNT/PANI) nanoribbon paper with volumetric capacitance (40.5 F.cm −3) and mechanical compliance toward bending and folding, maintaining electrochemical stability up to 1000 cycles has been reported by Dengteng Ge 10. The fabrication of a yarn of carbon nanotubes filaments with 23 µm diameter for electrodes of supercapacitors has been reported by F. Liu 11 and co-workers. ...

“…For example, FeCl 3 has been used to initiate the polymerization of PPy and PEDOT on cellulose papers to fabricate electrodes for SCs [ 181 ] and batteries. [ 183 ] Figure 14g shows the GO‐doped elastic PU nanofiber membrane functionalized by in situ PEDOT polymerization using FeCl 3 oxidant for pressure and strain sensing. [ 191 ] After polymerization, the 3D porous network structure of the substrate is well preserved, and the nanofiber surface is conformally coated with PEDOT, thus providing a large deformation space and more contact sites.…”

With the advent of the Internet of Things era, the connection between electronic devices and humans is getting closer and closer. New‐concept electronic devices including e‐skins, nanogenerators, brain–machine interfaces, and implantable medical devices, can work on or inside human bodies, calling for wearing comfort, super flexibility, biodegradability, and stability under complex deformations. However, conventional electronics based on metal and plastic substrates cannot effectively meet these new application requirements. Therefore, a series of advanced electronic devices based on flexible porous substrates (e.g., paper, fabric, electrospun nanofibers, wood, and elastic polymer sponge) is being developed to address these challenges by virtue of their superior biocompatibility, breathability, deformability, and robustness. The porous structure of these substrates can not only improve device performance but also enable new functions, but due to their wide variety, choosing the right porous substrate is crucial for preparing high‐performance electronics for specific applications. Herein, the properties of different flexible porous substrates are summarized and their basic principles of design, manufacture, and use are highlighted. Subsequently, various functionalization methods of these porous substrates are briefly introduced and compared. Then, the latest advances in flexible porous substrate‐based electronics are demonstrated. Finally, the remaining challenges and future directions are discussed.

The performance of nata de bamboo (NDB) and nata de chayote (NDCh) membranes as zinc-carbon battery separators has been investigated. NDB and NDCh are bacterial cellulose produced from a fermentation process by bacterium acetobacter xylinum on bamboo shoots and chayote substrate, respectively. Two types of membranes, i.e., complete sheet (type 1) and homogeneous (type 2) from both natas were fabricated with various weights. The membranes were pressed, dried, and placed on the zinc-carbon battery as a separator. The digital caliper was used to measure the thickness of the membranes. The electrochemical properties of the membranes as zinc-carbon battery separators were observed by Linear Sweep Voltammetry (LSV) and Electrochemical Impedance Spectroscopy (EIS) techniques. A comparison study was conducted with an original membrane separator of a zinc-carbon battery. The results showed that the thickness of type 1 membranes from both NDB and NDCh in all variations is thinner than that of type 2 membranes and original membranes. NDB and NDCh membranes' resistance was similar to the original membrane separator. The best result was achieved from type 1 of NDB and NDCh membranes. This indicates that NDB and NDCh membranes have the potency to replace an original membrane separator of zinc-carbon batteries.
