“…Table 1 demonstrates that all polymer-cotton fabric composite samples have improved thermoelectric properties in terms of lowering the cotton thermal conductivity to the range of 0.001-0.007 W m −1 K −1 and increasing the electrical conductivity to the range of 1-30 s m −1 . This is a great improvement to previous studies, where for example, the electrical conductivity of cotton fabric was increased to 0.06 s m −1 at best by Güneşoğlu et al [61] by coating with PANI/Co@C-coated metal nanoparticles. There is a lack of thermal conductivity data in the literature for polymer-cotton fabric or other natural fabric composites.…”

A thermoelectric wearable is proposed based on an innovative 3D wearable design, with p-type polymer impregnated cotton yarns and n-type polymer impregnated cotton yarns, where the ratio of the p-/n-type yarn cross-sections is optimised to maximise the thermoelectric conversion efficiency. The thermoelectric yarns are embroidered through a double-layer cotton fabric, using plain-stitch, and connected via painted silver electrodag patches. The first stage of this study involved the characterisation of P3HT-, PEDOT:PSS-and PCBM-cotton fabric composite samples, in terms of their fibre volume fraction, specific heat capacity, thermal conductivity, electrical conductivity, Seebeck coefficient, Z and power factors. In this initial assessment, P3HT was selected as the p-type polymer compared to PEDOT:PSS, and PCBM was selected as the n-type polymer. A small, 3D wearable prototype was fabricated and tested: it exhibited a Seebeck coefficient of 380 μV K −1 but a relatively high resistance. It was estimated that scaling up this thermoelectric wearable to body coverage would produce about 1.5-2 μW for a temperature difference of 40 °C applied on the thermoelectric device.

“…Cotton fabrics are ideal for the creation of smart textiles because they are very comfortable to wear, have high absorbency and hydrophobicity, are inexpensive, and are resistant to static electricity [ 11 ]. In general, conductive cotton fabrics can be easily produced using three methods [ 12 ]: infusion with nanomaterials [ 13 ], coating with conductive polymers [ 14 ], or coating with conductive polymers and nanomaterials [ 15 ].…”

With the rapid growth of electronic textiles, there is a need for highly conductive fabrics containing fewer conductive materials, allowing them to maintain flexibility, low cost and light weight. Poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS), is one of the most promising conductive materials for the production of conductive fabrics due to its excellent properties such as solubility, relatively high conductivity, and market availability. Moreover, its electrical conductivity can be enhanced by polar solvents or acid treatment. The aim of this work was to fabricate conductive cotton fabrics with a small fixed amount of PEDOT:PSS and to investigate how titanium dioxide (TiO2) nanoparticles affect the electrical, thermal and structural properties of PEDOT:PSS-coated cotton fabrics. The change in electrical conductivity of the nanocomposite fabric was then related to morphological analysis by scanning electron microscopy and X-ray diffraction. We found that the sheet resistance of the nanocomposite cotton fabric depends on the TiO2 concentration, with a minimum value of 2.68 Ω/□ at 2.92 wt% TiO2. The effect of UV light on the sheet resistance of the nanocomposite cotton fabric was also investigated; we found that UV irradiation leads to an increase in conductivity at an irradiation time of 10 min, after which the conductivity decreases with increasing irradiation time. In addition, the electrical behavior of the nanocomposite cotton fabric as a function of temperature was investigated. The nanocomposite fabrics exhibited metallic behavior at high-TiO2 concentrations of 40.20 wt% and metallic semiconducting behavior at low and medium concentrations of 11.33 and 28.50 wt%, respectively. Interestingly, cotton fabrics coated with nanocomposite possessed excellent washing durability even after seven steam washes.

“…Such transformation involves non-redox doping, in which a polaron conduction band, with most of the positive charge residing on the nitrogen atoms, is responsible for the electrical conductivity. PAni's doping process produces a nice color range from blue to green, which is useful for developing electrochromic devices, which is further favored by its good environmental stability (27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39). PAni has been one of the most studied polymers for the past 20 years.…”

Polyaniline is a conductive polymer that attracts the attention of many researchers around the world. The history of this polymer begins in 1862 when Letheby first reported this material. Since then, a myriad of studies has been conducted onthis material, and new works continue to investigate the potential of this material. Polyaniline has been improved with the help of Nanotechnology. The use of nanofillers has been seen as a quick and economical way to modify materials, drivinginnovations based on new physical and chemical properties from the conductive polymer materials and nanoparticles joining. Several works address the use of different nanoparticles, which leads to the practical impossibility of sifting through all this information. Thus, this work proposes to systematically collect data in the literature and investigate which nanoparticles can increase the electrical conductivity of Polyaniline (PAni). The results obtained demonstrate that among the possiblenanofillers, graphene and carbon nanotubes have great prominence. Furthermore, the results of the meta-analysis prove that PAni's conductivity increases when this polymer is modified with the aforementioned nanofillers.
