Abstract
Silver nanowires (AgNWs) have been considered as a promising candidate for transparent stretchable conductors(TSCs). However, the strong interface mismatch of stiffAgNWs and elastic substrates leads to the stress concentration at theirinterface and ultimately the low stretchability and poor durability of TSCs. Here, to address the interfacial mismatch of AgNWs-based TSCs we put forward a universal interface tailoring strategy that introduces the mercapto compound as the intermediate cross-linked layer. The mercapto compound strongly interacts with the AgNWs, forming a dense protective layer on their surface toimprove their corrosion resistance, and reacts with the polymer substrate, forming a buffer layer to release the concentrated stress. Asa result, the optimized TSCs showed superior stretchability (160%), exceptional durability (230 000 cycles), competentoptoelectrical performance (18.0 ohmmiddotsq-1with a transmittance of 86.5%), and prominent stability. This work provides clearguidance and a strong impetus for the development of transparent stretchable electronic
