Fabrication of Metallic Nanomesh: Pt Nano-Mesh as a Proof of Concept for Stretchable and Transparent Electrodes

Two-dimensional ordered arrays of honeycomb morphology of platinum are fabricated by using anodized aluminum oxide template and metal sputtering methods. The resulting metal films are highly conductible (71 Omega/sq), stretchable (16.8%), and transparent (75.2% at 550 nm). The presented synthetic strategy is scalable to large area without noticeable defects by incorporating the deposition of a thin layer of silver. In addition, both the pore size and wall thickness of platinum nanomesh films are straightforwardly controlled with sputtering time. As a proof of concept, the metal nanomesh films using AAO template suggest a new concept of synthesizing transparent and stretchable metal electrodes for future electronic devices.
