FORMATION OF ELECTRICALLY CONDUCTIVE LAYERS AT ROOM TEMPERATURE USING SILVER NANOPARTICULATE PROCESSING AND INKS FOR FORMING THE LAYERS

Resumen de: TW202417240A

Room temperature processing has successfully resulted in highly conductive coatings formed from silver nanowires with a cellulose binder. The conductive coatings can be formed with silver salts to fuse the silver nanowires into a unitary fused metal nanostructured network. Even without added silver salts, low sheet resistance values can be obtained. Room temperature processing can be effective over a range of transmittance values from highly transparent to modestly transparent to translucent to opaque. The ability to form the transparent coatings opens the processing to a wide range of substrates that are not processible with higher process temperatures.
