“…The peaks of PET/CO appeared at 1709 cm -1 , 1238 cm -1 , 1104 cm -1 , 1025 cm -1 were corresponding to stretching vibration of C=O, asymmetric stretching of aromatic ester, ring asymmetric stretching and stretching vibration of C-O respectively. The peaks between 3600 cm -1 and 3000 cm -1 represented the hydrogen bonded OH stretching (Carrillo et al 2004;Alimohammadi et al 2018;Palaskar et al 2011). After the final modification, the new peaks appeared at 1667 cm -1 , 1545 cm -1 , 1420 cm -1 , 1238 cm -1 , cm -1 , 827 cm -1 corresponding to the bond stretch of C=C, condensed aromatic ring O-H, carboxylic O-H, P-O-C aromatic stretching, C-OH stretching and P-CH2 bond, respectively (Carrillo et al 2004;Palaskar et al 2011;Gaan and Sun 2007;Gashti et al 2013a;Ren et al 2007;Gashti et al 2013b;Shin et al 1997).…”

Graphene has been highlighted in a variety of wearable electronics and smart textiles applications due to its unique properties such as high conductivity, transparency, flexibility and other excellent mechanical performance. Although there have been extensive efforts for graphene based conductive fibers/yarns, there are remaining challenges in terms of the seamless integration between 2D flakes, and reduced charge transport in a lower carrier concentration. Unstable resistance probably arises from the creation of gaps in the conductive parts of the smart textile. Also, regional temperatures can get too high, constituting a fire-safety hazard and endangering the wearer's safety. In this work, the synergistic effect of graphene and flame-retardant materials was investigated, and a conductive fabric was developed which is highly conductive and flame retardancy. Graphene has excellent electrical and thermal conductivity and acts synergistically with traditional flame-retardants on common fabrics. The electrical surface resistivity of hybrid material modified fabrics was as low as 0.54 kΩ/sq, so they could serve as safe and highly conductive conductor in a simple circuit and show excellent wash-ability. The limiting oxygen index of the fabric increased from 19 to 32 after modification in conjunction with the residue at 800 o C increased from 17.9% to 31%, which could be used as safe and highly conductive materials for smart textiles and wearable devices.

“…Water-soluble carbon nanotubes were functionalized in alkali and acidic solutions and then incorporated into a poly-vinyl alcohol (PVA) network followed by the coating of a polypropylene thread in order to improve its mechanical properties [21]. Recently, CNTs were dispersed in poly-vinyl pyrrolidone (PVP) medium and deposited onto cotton fabric using a curing method under UV-C irradiation [22]. In another recent study, a conductive super-hydrophobic cotton fabric was developed by assembling carboxylated and aminated multiwalled carbon nanotubes and modifying them with polydimethylsiloxane [23].…”

We propose a method of crosslinking multiwalled carbon nanotubes (MWCNTs) with cotton fabric. 3-Glycidoxypropyltrimethoxy silane (GPTMS) polymer was used for the stabilization and modification of the surfaces of MWCNTs. The presence of tannic acid in the finishing formulation adds a sustainable functionality to the treated surface. The formation of the GPTMS–MWCNTs nanocomposite as well as the MWCNTs–GPTMS tannic-epoxy nanocomposite on the fabric surface was confirmed by Fourier-transform infrared spectra (FTIR). The surface morphology and physical properties were investigated. An assessment of antibacterial activity, UV-protective properties, and electrical conductivity was performed. The post-treatment results of the MWCNTs–GPTMS nanocomposite fabric with tannic acid exhibited superior antibacterial character with the highest inhibition zones for Staphylococcus aureus and Escherichia coli (26 mm, 24 mm). On the contrary, the electrical conductivity was negatively impacted. The treatment of cotton fabric with tannic acid showed a great UV-protection-factor estimation of 96.2, which was additionally improved by treatment with MWCNTs 152.1. Cotton fabric treated with cotton/GPTMS/tannic acid/MWCNTs as well as cotton/GPTMS/MWCNTs recorded the highest electrical-conductivity properties. Fabrication of MWCNTs–GPTMS/tannic-acid-nanocomposite-coated cotton fabric for durable antibacterial and UV protection with improved electrical and physical properties was successfully achieved.

“…In recent years, numerous scholars have studied the surface modification of fabric and proposed a method of surface modification using polymer coating; for example, Alimohammadi et al proposed and prepared polyvinylpyrrolidone/carbon nanotube/cotton nanocomposite (polyvinylpyrrolidone/carbon nanotube/cotton) coated cotton fabric and studied the functionality and durability of the composite. 27 Gashti et al prepared a polyvinyl phosphonic acid/carbon nanotube composite coating to induce flame-retardant cellulose fibers with ultraviolet radiation. Carbon nanotubes were deposited on the surface of cotton using vinyl phosphonic acid monomer as the crosslinking agent and benzophenone as the catalyst.…”
