Estimating the term…
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.
A method for forming a conductive layer comprising:
An ink for forming a conductive layer, the ink comprising from about 0.001 wt % to about 4 wt % metal nanowires and from about 0.05 wt % to about 5 wt % of a hydroxy alkyl-functionalized polymeric binder, aqueous solvent comprising from about 20 vol % to about 100 vol % of a C1 to C10 alcohol, and no more than about 0.001 wt % of a surfactant.
