Case Study

Development of High-Performance Conductive PEDOT-Coated Modified Polyester Yarn

Tariq Bashir, et al.. Polymers for advanced technologies, 2012, 23(3), 611-617.

The preparation of high-performance conductive polyester yarn was achieved by coating the conjugated polymer poly (3,4-ethylenedioxythiophene) (PEDOT) on flexible high-strength polyester yarn using oxidative chemical vapor deposition (OCVD) technology. The PEDOT-coated conductive polyester yarn has potential in smart clothing for medical and military applications.
Preparation procedure of PEDOT-coated polyester yarn
· The process of oxidative chemical vapor deposition of PEDOT entailed three main steps. Firstly, the polyester (PET) yarns, cut to a length of 150 mm, were soaked in a solution of 15 wt% ferric (III) chloride in butanol and left to dry.
· Subsequently, the yarns, now enriched with oxidant, were introduced into a tubular deposition reactor. Here, they were exposed to vapors of the EDOT monomer, which were introduced alongside nitrogen gas from a separate flask. As the oxidant-enriched fibers interacted with the EDOT monomer vapor, a polymerization reaction was initiated spontaneously, resulting in the fibers being coated with a dark blue layer of PEDOT.
· Following polymerization, the PEDOT-coated yarns underwent a doping process by treatment with a 3 wt% FeCl3 solution. They were then washed multiple times with methanol to eliminate any unreacted EDOT monomer, FeCl3 oxidant, and byproducts before being air-dried at room temperature.

Preparation of Flexible Polyester Yarn/Gold/Conductive MOF Composites

Yang, Shi-Yi, et al. Journal of Electroanalytical Chemistry, 2019, 847, 113218.

In order to develop flexible yarn-like supercapacitors for wearable electronics, a conductive MOF material was coated on the surface of gold-coated polyester yarn (PET/Au) to improve the electrochemical performance. The results showed that the obtained yarn supercapacitor provided a high length capacitance of 113.6 mF/cm at a current density of 0.1 mA/cm and an energy density of 3.94 μWh/cm.
Fabrication of PET/Au/Ni-MOF@carbon yarn electrode materials
· The preparation process of PET/Au yarns begins with commercial PET yarns being cleaned in a 1.0 M NaOH solution at 60°C for one hour, followed by ultrasonic cleaning with deionized water and drying in a vacuum oven at 60°C.
· A 6.0 mM dopamine solution is created by dissolving 74 mg of DA in 65 mL of DI water, adjusting the pH to 8.5. The PET yarns are then immersed in the dopamine solution for 24 hours at room temperature, cleaned with DI water, and dried again. The polydopamine (PDA) modified PET yarn is then treated with a SnCl2·2H2O solution and rinsed thoroughly.
· Next, a solution containing 5.0 mM HAuCl4 is buffered to a pH of 11.0 and mixed with EDTA. The sensitized PDA yarn is submerged in the HAuCl4 solution with stirring, while a glucose solution is slowly added to form the PET/Au yarn.
· Moving on to the fabrication of PET/Au/Ni-MOF@carbon yarn electrodes, a slurry of Ni3HHTP2 powder, acetylene black, and PVDF in NMP solution is coated onto a PET/Au yarn and dried in a vacuum oven to create PET/Au/Ni-MOF@carbon electrodes.
