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
toward oxidation for more than 2 months while keeping the same intrinsic
conductivity as in bulk silver.
