Metal mesh is one of the contenders to replace indium tin oxide as transparent conductive electrodes, and interestingly they can be bent by changing the substrate. Such new structure is reported, featuring a metal mesh fully embedded and mechanically anchored on a flexible substrate, and a cost-effective solution-based fabrication strategy. And this electroplating-transfer method produces metal meshes whose geometric features are predefined by photolithography process, without high temperature or any vacuum processes. In particular, this strategy enables an improved conductivity without sacrificing transparency by changing line-width or others. Using this technique, a number of metal mesh is demonstrated with transmittance of 88% and sheet resistance of 5Ω/□, and high figure of merit over 600 at line-width of 5um and line-spacing of 500um. Finally using our metal mesh, a flexible transparent thin-film heater is demonstrated with a low power density requirement and operating voltage. |
