Highly oriented woven Ag-NW grids has great potential for enhancing the mechanical stabilities of flexible transparent electrodes (TEs) but few researchers reported. This work presents a flow driven self-assembly approach for preparing the highly oriented woven Ag-NW grids. Due to the coupling effect of micro-structured silicon mold and thermocapillary flow induced by surface tension, two flow states of Ag-NWs ink are formed in sequence, which leads to the enrichment of Ag-NWs. Meanwhile, the selective deposition enables the highly oriented woven feature of Ag-NWs. Using elastomer casting and transferring processes, TEs of Ag-NWs embedded in PDMS are successfully obtained. Such TEs show remarkable mechanical performances with a low sheet resistance of ∼20 Ω/□. The change of resistance is less than 0.8% even under the extreme bending deformation. A resistance increase of less than 2.9% is observed when the sample undergoes 14,000 cycles. The stretching results also demonstrate excellent mechanical performance. The uniform electroluminescence of electroluminescent device under the flat and bending states verified that a defect-free TE have been fabricated. These results imply that the as-fabricated electrode is a promising candidate for flexible optoelectronic applications.
