Intrinsically Healable and Photoresponsive Electrospun Fabrics: Integrating PVDF-HFP, TPU, and Azobenzene Ionic Liquids

MIM][TFSI] enable intrinsic self-healing and light-induced responsiveness, while the incorporation of TPU prevents fiber fusion during electrospinning, maintaining structural integrity and porosity. Our results demonstrate that these fabrics can recover up to 97% of their original mechanical properties after self-healing and exhibit reversible changes in electrical conductivity under UV and visible lights. This versatile approach paves the way for the incorporation of high concentrations of functional ionic liquids into electrospun fabrics, enabling the development of multifunctional textiles with potential applications in self-healing wearable devices and advanced sensors.
