Abstract

Abstract : A pre-strain strategy was applied to 1-D conductive cords, significantly enhancing the stretchability and bendability of 1-D conductive cords with stable retention of conductivity. Abstract : A highly stretchable and foldable conductive cord was developed by depositing silver nanowires (AgNWs) on a polyurethane cord. The application of pre-strain to the cord during the deposition of AgNWs resulted in the formation of a wrinkled AgNW layer, thereby inducing structural stability towards stretching and bending. This conductive cord exhibited stable electric conduction under strain values of up to 167% and at a bending radius of 0.3 mm. Also, it could withstand a stretching test of 500 cycles at a strain of 50%.
