文摘

Ag mesh electrode was researched as a replacement for indium–tin oxide electrode in flexible electronics because of its low sheet resistance and high transparency. In this study, Ag mesh pattern created using Ag nanoparticles (20?nm of diameter) was arranged on a patterned polymer substrate using thermal roll-to-roll imprint lithography. Using this method, the Ag mesh-patterned electrode achieved scalability and high throughput. The fabricated Ag 3D mesh electrode showed an average optical transmittance of 69?%, and sheet resistance of 18?Ω/sq was measured for 60?min of annealing time.
