20150144380 | TRANSPARENT CONDUCTIVE COATINGS BASED ON METAL NANOWIRES AND POLYMER BINDERS, SOLUTION PROCESSING THEREOF, AND PATTERNING APPROACHES - Polymer binders, e.g., crosslinked polymer binders, have been found to be an effective film component in creating high quality transparent electrically conductive coatings or films comprising metal nanostructured networks. The metal nanowire films can be effectively patterned and the patterning can be performed with a high degree of optical similarity between the distinct patterned regions.

After fusing the network can provide desirable low sheet resistances while maintaining good optical transparency and low haze. A polymer overcoat can further stabilize conductive films and provide desirable optical effects. The patterned films can be useful in devices, such as touch sensors. | 05-28-2015 |
