Production of high performance conductive textile yarn fibers for different electronic applications has become a prominent area of many research groups throughout the world. We have used oxidative chemical vapor deposition (OCVD) technique to coat flexible and high strength polyester yarns with conjugated polymer, poly(3,4ethylenedioxythiophene) (PEDOT) in presence of ferric (III) chloride (FeCl 3 ) oxidant. OCVD is an efficient solvent free technique used to get uniform, thin, and highly conductive polymer layers on different substrates. In this paper, PEDOT-coated polyester (PET) yarns were prepared under specific reaction conditions, and the electrical, mechanical and thermal properties were compared to previously studied PEDOT-coated viscose yarns. Scanning electron microscopy (SEM) and FT-IR analysis revealed that polymerization of PEDOT on the surface of the polyester yarns has been taken place successfully and structural analysis showed that PEDOT has strong interactions with viscose yarns as compared to PET yarns. The voltage-current (V-I) characteristics showed that PET yarns are more conductive than PEDOT-coated viscose yarns. The variation in the conductivity of PEDOT-coated yarns and the heat generation properties during the flow of current through coated yarns for longer period of time, was studied by time-current (t-I) characteristics. Thermogravimeteric analysis (TGA) was employed to investigate the thermal properties and the amount of PEDOT in PEDOT-coated PET yarns compared to PEDOT-coated viscose. The effect of PEDOT coating and ferric (III) chloride concentration on the mechanical properties of coated yarns was evaluated by tensile testing. The obtained PEDOT-coated conductive polyester yarns could be used in smart clothing for medical and military applications.

“…Although the polymerization conditions were changed, the highest PAn–PTh content (%) of composite fibers was 2% and the lowest surface resistivity was measured as 24 MΩ/cm 2 . This resistivity value was higher than that from PAn/PET and PTh/PET conductive composite fibers reported in our previous studies; consequently, the PET samples were swollen in dichloromethane which is known as a swelling agent for PET fibers, at boiling temperature for 2 h, and these fibers were used in experiments.…”

A conductive polyaniline (PAn)-polythiophene (PTh)/poly(ethylene terephthalate) (PET) composite fiber was prepared by polymerization of aniline and thiophene in the presence of PET fibers in an organic medium with FeCl 3 . The effects of polymerization conditions, such as polymerization medium, mol ratios of aniline/thiophene and FeCl 3 /aniline-thiophene as well as polymerization temperature and time, were investigated on PAn-PTh content (%) and surface resistivity of the composite. The composite with the lowest surface resistivity (1.30 MX/cm 2 ) was obtained by polymerization of aniline and thiophene (1/3 mol ratio) in acetonitrile/ chloroform (1/5 volume ratio) at 20 C. The surface resistivity of the PAn-PTh/PET composite containing 4.8% PAn-PTh was increased from 1.9 MX/cm 2 to 270 MX/cm 2 at pH 11. The washing durability of the composites was determined with domestic and commercial laundering processes by monitoring the surface resistivity and morphology. The composite was also characterized with FTIR, TGA, elemental analysis, optic microscope and SEM techniques.

“…Three types of materials have been explored for the fabrication of high-conductivity textiles: polymer-based, carbon-based, and metallic materials [1]. The electronic textiles can be achieved through the introducing of conductive polymers such as polyaniline (PANI) [9,10], polypyrrole (PPy) [11], polythiophene (PT) [12]; also, via electrochemical, or chemical polymerization processes [13,14]. PANI has been defined to be the first dispersible essentially conductive polymer readily accessible and stable in ambient conditions [15].…”

In this study, cotton fabric was employed to achieve electronic textile by incorporating nano MnO2 and polyaniline as conductive materials. The treatment was accomplished via two consecutive steps, where different concentrations of MnO2 were initially applied by the ultrasound-assisted template method onto the cotton samples to synthesize nanoMnO2. The nano form of the metal oxides and polyaniline inclusion were demonstrated through a transmittance electron microscope. Thereafter, chemical oxidative polymerization of aniline over the nano metal oxide–loaded fabrics was performed. Structure, phase, and purity of as-treated fabrics were determined using X-ray diffraction and Fourier transform infrared spectroscopy. The thermal properties of the fabricated conductive samples were also tested. The electrical conductivity of the obtained (nano MnO2/polyaniline) modified cotton fabrics showed great enhancement by exposing the modified samples to gamma irradiation, as a posttreatment, to reach an optimum condition at 40 kGy, using 0.2 M MnO2. The recorded increment for electric conductivity was from 5.4 × 10−3 to 1.43 × 10−1 Ω−1. m−1 for both unirradiated and 40 kGy irradiated samples, respectively. Pseudo-capacitance of cotton/MnO2/polyaniline fabric electrode was tested using a three-electrode system. The assumption of (nano MnO2/polyaniline) cotton fabric conductivity was verified through a designed pseudo-capacitor as an important yet simple form of an energy storage device.
