Abstract:
Reduction/oxidation reagents have been found to be effective to chemically cure a sparse metal nanowire film into a fused metal nanostructured network through evidently a ripening type process. The resulting fused network can provide desirable low sheet resistances while maintaining good optical transparency. The transparent conductive films can be effectively applied as a single conductive ink or through sequential forming of a metal nanowire film with the subsequent addition of a fusing agent. The fused metal nanowire films can be effectively patterned, and the patterned films can be useful in devices, such as touch sensors.
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.

Provided is a conductive film having a high conductivity in which electric resistance is less likely to increase, and a conductive composition for forming the same. The conductive composition includes an elastomer component, a fibrous carbon material having a fiber diameter of less than 30 nm, and a flake-like carbon material having a graphite structure, having an intensity ratio (G/D ratio) of a peak (G band) appearing in the vicinity of 1580 cm -1 to a peak (D band) appearing in the vicinity of 1330 cm -1 of Raman spectrum of not less than 1.8, and having a maximum length of not less than 150 nm and a thickness of not more than 100 nm. The conductive film is formed from the conductive composition.
