摘　　要：以具有优异弹性的氨纶作为基底,将具有良好导电性和柔性的碳纳米管薄膜以不同的包覆角度和层数缠绕在氨纶上,通过调节碳纳米管薄膜交叠层数、包覆角度以及采用聚苯胺、纳米银线等作为夹心层,制得的银纳米线包覆的夹心型碳纳米管/氨纶复合导线的电阻率变化最小,在拉伸45%条件下电阻变化率仅为0.71%。有望在可拉伸电子器件领域得到广泛的应用。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.
