The article introduces a multifunctional electronic textile based on biological phytic acid-doped nanocomposites, which exhibit high sensing performance and environmental friendliness. This electronic textile can be widely used in human-machine interactions, environment monitoring, and flame retardance.
Flexible sensors are the footstone of the internet-of-things as they combine one with the real world. However, to date, it's still a challenge to fabricate multifunctional and reliable sensors with ease of approach and eco-friendly materials. Herein, a multifunctional electronic textile based on biological phytic acid-doped hierarchically structured polyaniline/protein fabric nanocomposites, is presented. Benefiting from its property of transition in doping and de-doping state, the E-textile exhibits practicability in human-machine interactions, environment monitoring, and flame retardance. Owing to the construction of microfibers conductive network, the E-textile presents high strain sensitivity and ultralow detection limit (0.1% of strain) for monitoring tiny-human motions accurately. Meanwhile, it exhibits speedy response to ammonia (1.3 s) and excellent flame retardance which can work steadily after the fire treatment. This novel and sustainable strategy of preparing high-performance devices with bio-materials broaden the opportunities for the development of eco-friendly functional materials and devices.
