Silver nanowire (Ag NW) is a most dominant material for stretchable transparent electrode due to its excellent optical and electrical properties and it is also recognized as a promising candidate in various optoelectronic devices. Although many studies in the stretchable electronics have been used a prestraining substrate method for wavy structures, this method causes cracks to AgNWs with low yield strain during releasing substrate. To improve performance of AgNW networks, we propose a facile fabrication process based on the in-plane wavy Ag NW networks by combining the conventional pre-strain method with a solvent annealing system. To demonstrate this concept, we fabricated stretchable transparent alternating current electroluminescent (ACEL) device using wavy AgNW networks. The resulting ACEL device shows high luminescent performances under 50% of elongated strain and long cycle life of 1000 cycles of 50% strain.
