Functional textiles received considerable attention both in scientific field and in the market since late 2000s. Thanks to the developments in nanotechnology, functional textiles have been evolving into smart textiles. In addition to powering the smart textiles, improvement of their washing stability has utmost importance. Currently, batteries are used as the energy sources of smart textiles. However, there are cases where batteries do not fulfill the consumer needs. Moreover, integration of batteries onto the conventional clothes without reducing the consumer comfort is almost impossible. As a consequence, self-powered systems using triboelectric nanogenerators (TENGs) are evolved as strong alternatives to battery powered smart textiles. Silver nanowires are known to impart antibacterial activity [1] and heatability [2] to the textiles. In this study, silver nanowire (Ag NW) decorated fabrics are used as current collectors for the realization of wearable TENGs. Thermoplastic polyurethane (TPU) was deposited onto Ag NW decorated textiles and used as both the dielectric and protection layer. Simple dip and drying method was used for the deposition of both Ag NWs and TPU. The overall structure was used as a single electrode for wearable TENGs, where an open circuit voltage and short circuit current of 30 V and 4 µA were measured, respectively. TENGs were connected in series to further improve the output power. TPU overcoating was also demonstrated to enhance the washing stability of the Ag NW decorated fabrics. While the fabrics without TPU coating lost their conductivity after 10 washing cycles, TPU overcoated fabrics kept their conductivity up to 20 washing cycles.

SILVER NANOWIRE BASED MULTIFUNCTIONAL FIBERS AND FABRICS Doğanay, Doğa; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2022-11-23) The demand for functional textiles has been increasing for the last two decades. In particular, advancements in the internet of things, artificial intelligence and data science have forced scientists and engineers to develop better functional and/or electronic textiles that meet consumer demands. However, due to some deficiencies, functional textiles could not reach their true potential. Some of these deficiencies can be addressed with practice-based approaches. On the other hand, there are also some univer...
Electrochromic conjugated polyheterocycles and derivatives-highlights from the last decade towards realization of long lived aspirations Günbaş, Emrullah Görkem; Toppare, Levent Kamil (2012-01-01) Polymer electrochromism has been considered one of the liveliest branches of conducting polymer research, a tradition continued in the last decade. We have witnessed numerous significant advances, making commercial applications closer than ever. This feature article highlights these advances by separating them into 3 sections. The material design section emphasizes the new molecular structures that have been utilized as electrochromic materials and their promising results. The color control of polymeric ele...
Microporous patterned electrodes for color-matched electrochromic polymer displays Aubert, Pierre-Henri; ARGUN, Avni A.; Çırpan, Ali; TANNER, David B.; REYNOLDS, John R. (American Chemical Society (ACS), 2004-06-15) The emergence of electroactive and conducting polymers offers new opportunities for the design of materials for electrochromic devices (ECDs). Of these, poly(3,4-alkylenedioxythiophene)s (PXDOTs) and their derivatives exhibit the most promising electrochromic (EC) properties. Here, we report the use of highly porous metallized membranes which allow the production of patterned, rapid-switching, reflective ECDs. Using poly(3,4-ethylenedioxithiophene) (PEDOT), poly(3.,4-propylenedioxythiophene) (PProDOT), and ...
Silver-nanowire-modified fabrics for wide-spectrum antimicrobial applications Doganay, Yoga; Kanicioglu, Akin; Coskun, Sahin; Akca, Gulch; Ünalan, Hüsnü Emrah (2019-02-28) Antimicrobial textiles received considerable attention due to public health and personal hygiene concerns. On the other hand, pathogenic microorganisms gain immunity against existing antibacterial products. For these reasons, new and stronger antibacterial agents need to be developed immediately. In this work, silver nanowires (Ag NWs) were decorated onto conventional fabrics via facile and scalable dip and dry method. Antimicrobial activity of the nanowire-decorated fabrics was investigated against a Gram-...
2-acrylamido-2-methyl-1-propanesulfonic acid -methacrylic acid copolymer and its polyethylene glycol methyl ether derivatives as superplasticizers in concrete Tuzcu, Gözde; Aras, Leyla; Department of Polymer Science and Technology (2008) Polymers in concrete have received considerable attention over the past 30 years. Superplasticizers are one of the admixtures which have polymeric structure. In this study, polycarboxylate type slump-releasing dispersant, which is a copolymer of 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) and methacrylic acid (MAA), was synthesized in different feed compositions. The synthesis procedure of this copolymer was retrieved from literature. The derivatives of this water-soluble copolymer (AMPS-MAA) were s...
