Abstract

The mechanical stability of transparent and stretchable electrode materials is essential for their application in stretchable electronic devices. In this work, single-walled carbon nanotube (SWCNT)–silver nanowire (Ag NW) composite films were developed as electrode materials to improve the thermal stability and anti-electromigration characteristics of transparent stretchable film heaters. By adjusting the mixing ratio of SWCNT–Ag NW suspensions, the mechanical and anti-electromigration properties of SWCNT–Ag NW composite films were systematically investigated. Compared to pristine Ag NW film, the 75:1 SWCNT–Ag NW composite film exhibited an excellent thermal stability, improved anti-electromigration properties, and low sheet resistance of 62.3 Ω/sq with an optical transmittance of 83.4%. Moreover, the same composite film prepared on VHB substrate showed only 23.2% increase in the relative sheet resistance after 1000 times of stretching cycles under the tensile stress. Furthermore, the stretchable film heater with 75:1 SWCNT–Ag NW composite electrode exhibited an improved thermal and mechanical stability even after being exposed to 1000 stretching cycles with a peak strain of 200%.
