Silver nanowires (Ag-NW) assembled in interdigitated webs have shown an applicative potential as transparent and conducting electrodes. However, upon integration in practical device designs, the presence of silver oxide, which instantaneously forms on the Ag-NW surfaces in ambient conditions, is unwanted. Here, we report on the functionalization of Ag-NWs with 4-nitrophenyl moieties through A-C bonds using a versatile two step reduction process, i.e. ascorbate reduction combined electrografting. We show that 40 % of the Ag atop sites were terminated and provide high surface stability towards oxidation for over two months while keeping the same intrinsic conductivity as in bulk silver.
