Electronic textiles (E-textiles) have been an area of intense industrial and academic research for years due to their advanced applications. Thus, the goal of this study was to develop highly conductive silk fibroin electrochromic nanofibers for use in E-textiles. The silk nanofibers were prepared by an electrospinning technique, and the conductive polyaniline (PANI) was added to impart the electrical conductivity and electroactive property to the resultant electrospun silk composite nanofibers. The experimental results showed that tuning the electrospinning procedure could control the morphology of the composite nanofibers, thus altering their mechanical properties and surface wettability. Furthermore, the developed PANI/silk composite fibers possess electroactive and electrochromic properties, such as adjusting the applied voltage. The developed strategy demonstrated the feasibility of incorporating not only electrical functionality but also electroactivity into sustainable silk nanofibers using electrospinning technique.
多年来，由于其先进的应用，电子纺织品（E-textiles）一直是工业和学术研究的热点领域。因此，本研究的目标是开发用于电子纺织品的高导电丝素蛋白电致变色纳米纤维。通过静电纺丝技术制备丝纳米纤维，并添加导电聚苯胺（PANI），以使所得的静电纺丝丝复合纳米纤维具有导电性和电活性。实验结果表明，调整静电纺丝工艺可以控制复合纳米纤维的形态，从而改变其机械性能和表面润湿性。此外，所制备的聚苯胺/丝复合纤维具有电活性和电致变色特性，例如可调节施加的电压。所开发的策略证明了利用静电纺丝技术将电功能和电活性融入可持续丝纳米纤维的可行性。
