    • This invention relates to flexible, transparent and conductive coatings and films formed using single wall carbon nanotubes and polymer binders. Preferably, coatings and films are formed from carbon nanotubes (CNT) applied to transparent substrates forming one or multiple conductive layers at nanometer level of thickness. Polymer binders are applied to the CNT network coating having an open structure to provide protection through infiltration. This provides for the enhancement of properties such as moisture resistance, thermal resistance, abrasion resistance and interfacial adhesion. Polymers may be thermoplastics or thermosets, or any combination of both. Polymers may also be insulative or inherently electrical conductive, or any combination of both. Polymers may comprise single or multiple layers as a basecoat underneath a CNT coating, or a topcoat above a CNT coating, or combination of the basecoat and the topcoat forming a sandwich structure. Binder coating thickness can be adjusted by changing binder concentration, coating speed and/or other process conditions. Resulting films and articles can be used as transparent conductors for flat panel display, touch screen and other electronic devices.
    • 本发明涉及使用单壁碳纳米管和聚合物粘合剂形成的柔性,透明和导电涂层和膜。 优选地,涂层和膜由应用于形成纳米级厚度的一个或多个导电层的透明衬底的碳纳米管(CNT)形成。 将聚合物粘合剂施加到具有开放结构的CNT网络涂层,以通过渗透提供保护。 这提供了诸如耐湿性,耐热性,耐磨性和界面粘合性等的增强。 聚合物可以是热塑性塑料或热固性材料,或两者的任何组合。 聚合物也可以是绝缘的或固有的导电的,或两者的任何组合。 聚合物可以包含单层或多层作为CNT涂层下的底涂层,或CNT涂层上面的顶涂层,或者底涂层和顶涂层的组合形成夹层结构。 粘合剂涂层厚度可以通过改变粘合剂浓度,涂布速度和/或其他工艺条件来调节。 所得薄膜和制品可用作平板显示器,触摸屏和其他电子设备的透明导体。
