Green Synthesised Silver Nanocomposite for Thermoregulating E-Textiles

Personal thermal management devices provide a behaviourally aligned route to address dependence on energy-intensive heating and cooling systems. E-textiles form an ideal foundation for these devices. In this study, a Joule heating e-textile has been developed using green synthesised silver nanoparticles and polypyrrole, which can easily be dip-coated onto an environmentally benign linen fabric. A Plackett–Burman design was used to optimise the nanoparticle synthesis. Characterisation and electrothermal analysis were carried out to confirm the successful synthesis of silver nanoparticles (40–80 nm, polydispersity index (pdi): 0.25) and an electrical resistance of 28.5 Ω. Joule heating of 66 °C at 6 V applied DC voltage was attained.
