By fabricating a silver nanowire network in this way, the research team was able to stretch the substrate and its nanowires by at least 50% of the initial length, stably maintaining transparency and conductivity for approximately 5,000 stretching-relaxing cycles. The team also found that this type of material could be produced using an inexpensive and environmentally-friendly process that uses ethanol and water as solvents.
"The stretchable and transparent electrodes made using wavy silver nanowire networks developed through this research have a high degree of electrical conductivity that is not changed by any deformation", said Dr. Sang-Soo Lee at KIST
"Since the technology can be used for mass production, it is expected to have a great impact on markets related to wearable electronic devices, such as high-performance smart wear, and the medical equipment field", added KIST's Dr. Jeong Gon Son.
