Resumen de: CN119654235A
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.
