Resumen de: US2023398802A1
A solvent layer is coated on a metal layer carried by a donor substrate, allowing the fabrication of solid metal lines at a high resolution. The laser jetting involves ejecting metal particles, constrained within a solvent membrane, from the metal layer. Once the metal particles have been deposited onto a receiver substrate, the solvent can be evaporated. Since this printing procedure can be performed with the solvent layer in direct contact with the receiver substrate or separated therefrom by a small distance, the resolution of the metal lines can be very high and depends directly on the laser spot size and defocus. The solvent constrains the droplet size of the metal particles, which can increase or maintain the resolution of the laser beam. As this process is a continuous sequence production, the metal line production can be performed at a very rapid rate.

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.
