Stretchable, transparent and molecular permeable honeycomb electrodes and their hydrogel hybrids prepared by the breath figure method and sputtering of metals

Abstract

We here describe a thin, highly stretchable transparent and molecular permeable porous electrode with a well-defined honeycomb structure fabricated by a combination of a bottom-up breath figure process and top-down sputtering of metals. Furthermore, the honeycomb electrode–hydrogel hybrids show higher durability, optical transparency, and electrical conductivity. The optical and electrical properties of the electrode, and its potential for use as a stretchable transparent electrode, are discussed.
