Method for processing metal nanowire ink with metal ions

A method for processing a deposited metal nanowire ink with metal ions, the method comprising:

• drying the deposited metal nanowire ink at a temperature from about 60° C. to about 99° C. at a relative humidity of at least about 40% for at least about 1 minute, wherein an electrically conductive film is formed comprising a fused metal nanostructured network, and wherein the deposited metal nanowire ink comprises a metal nanowire ink comprising from about 0.001 wt % to about 4 wt % metal nanowires, from about 0.05 wt % to about 5 wt % hydrophilic polymer binder, and from about 0.00025 wt % to about 0.5 wt % metal ions.
