Abstract: By using the highly stretchable spandex as the core,and winding CNT sheets around it under different angle and number of sheets,a novel stretchable conducting wire was prepared.By adjusting the number of winding CNT sheets,the angle,using polyaniline and nanosilver,etc.to make sandwich structure.The nanosilver sandwich structure had the smallest changes in resistivity and the resistance can change only by 0.71% at a tensile strain of 45%,showing great possibility for the application in stretchable electronic devices.
