    Abstract: 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. Metal nanostructured networks are formed through the fusing of the metal nanowires to form conductive networks. Methods for patterning include, for example, using crosslinking radiation to pattern crosslinking of the polymer binder. The application of a fusing solution to the patterned film can result in low resistance areas and electrically resistive areas. 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.

    Abstract translation: 已经发现,聚合物粘合剂,例如交联聚合物粘合剂,是产生高质量透明导电涂层或包含金属纳米结构网络的膜的有效膜组分。 可以有效地构图金属纳米线膜,并且可以在不同的图案化区域之间以高度的光学相似性进行图案化。 通过金属纳米线的融合形成金属纳米结构网络以形成导电网络。 用于图案化的方法包括例如使用交联辐射来模制聚合物粘合剂的交联。 将融合溶液应用于图案化膜可导致低电阻区域和电阻区域。 在融合之后,网络可以提供期望的低薄层电阻,同时保持良好的光学透明度和低雾度。 聚合物外涂层可以进一步稳定导电膜并提供所需的光学效果。 图案化的膜可用于诸如触摸传感器的装置中。
