“…At the moment, conductive textiles can be readily fabricated by depositing a layer of conductive metals on the textile surface by means of techniques such as galvanic deposition, atomic layer deposition, solution process of Al precursor composite, and electroless deposition (ELD). [6][7][8][9][10][11][12][13][14][15][16][17] Among these techniques, ELD is particularly attractive because it does not require expensive fabrication devices and can be carried out under ambient conditions on a large scale. [18][19][20] Previously, we have demonstrated the fabrication of conductive textiles by ELD of Cu and Ni onto various textile surfaces that have been modified with a thin layer of polyelectrolyte brushes.…”

This paper describes a fully aqueous- and air-compatible chemical approach to preparing high-performance conductive textiles. In this method, the surfaces of textile materials are first modified with an aqueous solution of double-bond-containing silane molecules to form a surface-anchoring layer for subsequent in situ free-radical polymerization of [2-(methacryloyloxy)ethyl]trimethylammonium chloride (METAC) in the air. Thin layers of poly-METAC (PMETAC) are therefore covalently grafted on top of the silane-modified textile surface. Cu- or Ni-coated textiles are finally fabricated by electroless deposition (ELD) onto the PMETAC-modified textiles. Parameters including polymerization time, temperature, and ELD conditions are studied to optimize the whole fabrication process. The as-made conductive textiles exhibit sheet resistance as low as 0.2 Ω sq(-1) , which makes them highly suitable for use as conductive wires and interconnects in flexible and wearable electronic devices. More importantly, the chemical method is fully compatible with the conventional "pad-dry-cure" fabrication process in the textile manufacturing industry, thus indicating that it is very promising for high-throughput and roll-to-roll fabrication of high-performance metal-coated conductive textiles in the future.

“…As such fibers are not very compatible with regular textile fibers from the point of view of processing (abrasion), product properties (hardness, stiffness), and behavior during normal use (separation of materials); soon it became clear that new conductive materials and structures had to be developed. In response new types of conductive materials were achieved by adding nanoparticles into the polymer, by combining elastic filaments with nonelastic conductive fibers [2], and by coating fibers with metallic layers [3].…”

“…To move forward in the area of etextiles, these electronic parts are being integrated on a textile substrate including wearable clothing to make wearable electronic structures [1][2][3][4][5][6][7][8]. Integration of electronics and cooperation of this industry with the textile industry to produce e-textile products based on specific user requirements is supposed to be booming in the near future this industry [9]. This new textile industry will probably produce a large number of garments and other textile objects connected electronically by 2020.…”

Protocol to assess the quality of transmission lines within smart textile structures

a b s t r a c tThe washability issue is always a challenge for electronic textiles in terms of application. It reduces their reliability, makes them not robust enough, and therefore not ready for the market. In this study, a novel protocol was designed to test the performance of conductive threads under wet situation in order to simulate the washing cycle. In this content, two commercially available silver-plated polyamide threads having the same thread count were used and washing results of each thread were discussed. Transmission lines with silver-plated polyamide threads onto cotton woven fabric were produced via sewing (single-line stitch) and embroidery techniques (three-line stitch) to improve the conductivity and robustness. For the simulation of the wash process, Martindale abrasion tester was used under wet and dry conditions. Moreover, felts of abrasion tester and transmission lines were put into different solutions, i.e., water, water with standardized detergent and water with commercially available detergent. After wetting specimens, abrasion tests were performed on transmission lines, and linear electrical resistance measurements were recorded with the multi meter before abrasion and every 1500 cycles up to 4500 cycles in wet conditions and also after drying the transmission lines. Finally, abrasion impact on silver-plated polyamide threads was investigated by optical microscope. It has been found that silver coating on the conductive thread was damaged when subjected to abrasion cycles, especially in wet states. Water itself has stress impact on samples provoking the electrical resistance increase rapidly. Commercial detergent with water was found to have the most damaging effect on the conductive threads because of extra particles presence to enhance the washing performance. In terms of integration methods, better electrical conductivity values were achieved in three-line embroidery transmission lines due to multiple interconnection points in the embroidery network.
