The rapidly evolving such devices are strongly pushing to develop stretchable conductors as an essential component that possess significant mechanical stretchability and high electrical conductivity at large strain. Therefore, there have been intensive researches for the stretchable conductors based on conductive materials such as carbon nanomaterials and metal nanostructures. In order to develop a universally applicable method for fabricating the geometrically designed polymer nanocomposite electrode, herein we report a gradient assembled polyurethane (GAP)-based stretchable electrode. We propose a new assembly concept, which can be called as 'composite-by-composite (CbC) aseembly' that has the advantages of both conventional vacuum-assisted filtration and layer-by-layer assembly methods. By using the stretchable electrode, we demonstrate stretchable aqueous batteries with high electrochemical performance under strain. |
