Highly stretchable and highly conductive metal electrode by very long metal nanowire percolation network

Abstract

A highly stretchable metal electrode is developed via the solution-processing of very long (>100 μm) metallic nanowires and subsequent percolation network formation via low-temperature nanowelding. The stretchable metal electrode from very long metal nanowires demonstrated high electrical conductivity (9 ohm sq -1) and mechanical compliance (strain > 460%) at the same time. This method is expected to overcome the performance limitation of the current stretchable electronics such as graphene, carbon nanotubes, and buckled nanoribbons. © 2012 WILEY-VCH Verlag GmbH & Co.
