Highly conductive woven fabrics (WF) can be used as electronic components. Resistivity is an intrinsic physical property of the conductive textile materials (CTM). The McLachlan model that describes the resistivity of a two-component macroscopic composite (TCMC) subjected to a constant external electric field was proposed to predict the resistivity of fabrics. The volume fraction of voids in material, the voids dimension, and a single morphology parameter were taken into account. The resistivity of a chosen WF was determined based on the model. Verification of the received results was carried out. In the case of four samples, the verification was confirmed by the high level of prediction being in the range of 83-88%. In the case of one sample, the verification was negative (26%). This allowed one to pay attention to the influence of compactness and irregularity of the woven structure on results received using the model.

A new synthesis of methacrylate end‐capped poly(3,4‐ethylenedioxythiophene) (PEDOT) was performed: the polymer is soluble in common organic solvents, thus overcoming the well‐known technical problems related to the use of commercial PEDOT in different printing technologies, such as screen printing, due to its poor processability and compatibility in formulations with other resins and polymers. The new synthetic method developed is based on the direct oxidative polycondensation of 3,4‐ethylenedioxythiophene (EDOT) in the presence of an oxidant species and a crosslinkable end‐capper, i.e., methacrylate end‐capped EDOT (mEDOT), prepared via Friedel Crafts acylation with methacryloyl chloride. The oxidative polycondensation between EDOT and mEDOT monomers in the presence of a new kind of doping agent, Sulfonated Polyarylethersulfone (SPES)—characterized by different degree of sulfonation (DS)—was conducted, leading to functional end‐capped conducting PEDOT (mPEDOT_SPES), with conductivity of 210 S/cm, 50 S/cm higher than the one of commercial PEDOT. Thanks to the enhancement of solubility, leading to better processability, end‐capped PEDOTs were formulated with a thermoplastic ink, Plastisol®, and electronic circuits were successfully screen printed on flexible cotton substrates, to obtain printed crosslinkable electronic circuits. The conductive features of mPEDOT_SPESs were successfully compared with the ones of PEDOT and of not‐doped end‐capped PEDOTs. POLYM. ENG. SCI., 57:491–501, 2017. © 2017 Society of Plastics Engineers

“…E-textile products have many applications, e.g., in biomedical sensors (electrocardiogram sensors), piezoresistive sensors, piezoelectric materials (optical resonator and transducer), rehabilitation (electromagnetic shields in physiotherapy) as well as professional sports and recreation (smart suits) (Rattfalt et al 2007;Zhou et al 2014;Capineri 2014;Usma et al 2015;Dias 2015). Modifiers such as silver, carbon, gold and copper are the most common conductors and can be combined with various textile materials using conventional and unconventional methods (Cieślak et al 2009;Stempien et al 2016;Shateri-Khalilabad and Yazdanshenas 2013;Cui et al 2015). In the last decade, much research has been dedicated to conductive textiles obtained by the application of carbon nanotubes Nasirizadeh et al 2015;Makowski et al 2015), graphene, graphene oxide (Shateri-Khalilabad and Yazdanshenas 2013; Shen et al 2016), carbon nanotubes and graphene oxide nanocomposites (Tang et al 2014) or conductive polymers such as polypyrrole (Nateghi et al 2013;Kim et al 2013) and polyaniline (Zhao et al 2013;Agarwal et al 2016) and conductive polymers such as PEDOT/PSS (Tarabella et al 2012).…”

Investigation on functionalization of cotton and viscose fabrics with AgNWs

et al. 2016

A study on the functionalization of cotton and viscose fabrics to achieve bifunctional conductive and antibacterial properties was carried out; 0.5 wt% AgNW ethanolic colloid was prepared, and fabrics were dipped and dried in the colloid 1, 10 and 15 times. After one dipping, both fabrics remained nonconductive, and the surface resistance (R s ) of cotton was 4.9 9 10 10 and of viscose 3.6 9 10 11 X. Excellent conductivity properties were shown in cotton fabric after 10 dippings (20 X) and in viscose fabric after 15 dippings (46 X). The Ag content of these fabrics was 53.3 and 52.3% (SEM/EDX analysis) and 13.77 and 14.12% (TG/DTG analysis) for cotton and viscose, respectively. XRD analysis revealed the presence of AgNWs on the fabric surface. FTIR/ATR, Raman and TG analysis confirmed the effects of modifications. The AgNW layers on both fabric surfaces were resistant to abrasion. After 50 washes of the modified cotton fabric, R s increased from 20 to 195 X. The AgNW layer was stable and the fabric still highly conductive. However, viscose fabric became nonconductive after two washes, and the surface resistance increased from 46 to 1.4 9 10 11 X. The tensile strength of cotton modified with AgNWs increased by about 49% and for viscose decreased by about 27%. AgNW-modified cotton fabric showed a significant antibacterial effect against S. aureus and K. pneumoniae bacteria. The presented method is more suitable for cotton because the modified cotton fabric retains the mechanical and conductive properties even after many washes.
