Claim Text:
1. A method of patterning a conductive electrode comprises providing a substrate, forming a film using a plurality of metal nanowires, wherein at least some of the metal nanowires are surface functionalized and inert to oxidation or acid reactions and the part of the film having the surface functionalized metal nanowires is a first region and the rest of the film is the second region, said surface functionalized metal nanowires have a first portion surface functionalized and a second portion that is not surface functionalized, wherein surface functionalization is a means for protecting the nanowire from oxidization and acid reactions; evaporating away solvent in the film; exposing the film to a chemical reagent which reacts with the metal nanowires in the second region; and annealing the film, wherein after annealing, the resistivity difference between the first and second region is more than 1000.
