Wet‐SpinningFabrication of Flexible Conductive Composite Fibers from Silver Nanowires andFibroin

Abstract：Biocompatible flexible conductivecomposite fibers have attracted great research interest because of multitude oftheir potential applications, such as wearable devices, biomedical sensors, andactuators. Herein, highly conductive and flexible silver nanowire(AgNW)/fibroin composite fibers were fabricated by using a wet-spinningtechnique. The composite fiber conductivity was as high as 5670S/cm at an AgNW concentration of29.1wt%. The composite fibers alsoexhibited high flexibilities and could be folded without losing theirconductivities. Furthermore, the composite fiber fabricated with a 3× drawratio exhibited a breaking strain of 27.3% and breaking stress of 118.1cN/dtex. Our attempt to produce such biocompatible flexible conductivecomposite fibers by using sustainable regenerated silk fibroins and compatibleAgNWs via wet spinning may provide a practical way for fabricating functionalbiocompatible fiber materials.
