Recently, silver nanowires (AgNWs) have had a great interest as a conducting materials for flexible and transparent electrodes. In this paper, we studied the embedded network structure formation of AgNWs in polydimethylsiloxane (PDMS) by stamping transfer process and various surface treatments. We have designed various conditions of AgNWs surfaces using silane-coupling modifiers. Transfer yield of AgNWs was adjusted by the variation of surface treatment condition with silane modifier coating such as methacryloxypropyltrimethoxysilane (MPS) and octadecyltrichlorosilane (OTS) on top of AgNWs. Transparency of embedded AgNWs film has increased up to 20% at the optimum surface treatment condition. Especially, MPS treatment process was found to be appropriate for thin film organic device substrate due to its generation of transferred AgNWs with low surface roughness. Transparent electrodes with OTS treatment showed resistivity with three times at 40% elongation at 200 cycle test. An organic solar cell with 3.2% of power conversion efficiency was fabricated with MPS-treated AgNW networks in a PDMS substrate.
