Transparent conductive nanoporous aluminium mesh prepared by electrochemical anodizing

A non‐lithographic method for the fabrication of the transparent conductive nanoporous aluminium (Al) mesh is presented. The electrochemical anodizing of Al layer deposited on the glass substrate was used to obtain the mesh. The average transmittance of 10–60% in 400–800 nm wavelength range and the sheet resistance of 10–1000 Ω sq−1 have been obtained for Al mesh with disordered pores arrangement. It was found that transmittance of uniformly arranged porous mesh is increased up to 80–90% with the conductivity range of 25–100 Ω sq−1. Our results demonstrate porous Al mesh as a strong candidate of low‐cost transparent conductive electrode, especially for flexible electronics
