Recently, the demand for technology in the field of wearable devices and portable devices that can be easily changed in form that can give innovation in the existing high-tech industry field is exploding. Accordingly, interest in stretchable, flexible, and foldable conductive films is greatly increasing. Among them, the stretchable electrode is important because it not only functions as an electrode, but also affects the performance of electronic devices and interconnects the components of the device system. Research on coating a conductive material on a flexible polymer substrate is being actively conducted. However, due to the limited stretchability of the existing substrate, a new stretchable substrate was required. Here, we fabricated a metal nanofiber network via electrospinning and metal deposition and immobilized the nanofibers on a bilayer composite polymer film. In addition, wrinkles were formed in the bilayer polymer film for use as a stretchable electrode.
