Room temperature processing has successfully produced a highly conductive coating formed from silver nanowires with a cellulosic binder. The conductive coating may be formed using a silver salt to melt the silver nanowires into an integrated fused metal nanostructured network. A low sheet resistance can be obtained even in the absence of an added silver salt. Room temperature processing may be effective in a transmittance value range from highly transparent to moderately transparent to translucent to opaque. The ability to form the clear coating makes it possible to process various substrates that cannot be processed at higher process temperatures.

A particle-free gold-complex based ink is described wherein a gold carboxylate is complexed with an amine. Upon heating the solution, the gold cation catalyzes the oxidative amidation of the amine with the carboxylate to form a short chain or polymeric amide while simultaneously reducing the gold cation to metallic gold. This method is extremely versatile and allows for both the preparation of pure metallic gold films as well as polymer gold composites with unique properties.
