    • The prior art has failed to provide an adequate method of producing a patterned nanowires network, for which the invention seeks a solution. To this end, it is proposed to provide a method of producing a patterned nanowires network, the method comprising the steps of: providing a nanowire donor film comprising a donor layer of nanowire material mixed with an adhesive epoxy; aligning a laser beam of a laser system and guiding the nanowire donor film distanced from a substrate surface; impinging the laser beam on the nanowire donor film; in such a way that the nanowire donor film is activated to cover a selected part of substrate surface with nanowire matter transferred from the donor layer; and wherein the laser beam is restricted in timing and energy, in such a way that the nanowire matter is sintered into a patterned nanowires network. Accordingly, a patterning method is provided, wherein the nanowire network can be transferred to an acceptor substrate with a desired pattern, and at the same time providing for a sintering process during transferring by suitable tuning of the patterned radiation.
    • 现有技术未能提供生产图案化纳米线网络的适当方法,本发明寻求解决方案。 为此,提出了制造图案化纳米线网络的方法,该方法包括以下步骤:提供纳米线供体膜,该纳米线供体膜包含与粘合剂环氧树脂混合的纳米线材料施主层; 对准激光系统的激光束并引导远离衬底表面的纳米线施主膜; 将激光束照射在纳米线供体膜上; 以使得纳米线供体膜被激活以覆盖从施主层转移的纳米线物质的衬底表面的选定部分; 并且其中激光束的时序和能量受到限制,使得纳米线物质被烧结成图案化的纳米线网络。 因此,提供了一种图案化方法,其中可以将纳米线网络转移到具有所需图案的受主衬底,并且同时在通过适当调谐图案化辐射的转移期间提供烧结工艺。

    • 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.
    • 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。
