Abstract
Fusing nanowire inks are described that can also comprise a hydrophilic polymer binder, such as a cellulose based binder. The fusing nanowire inks can be deposited onto a substrate surface and dried to drive the fusing process. Transparent conductive films can be formed with desirable properties.
Claims18
A metal nanowire ink comprising aqueous solvent, from about 0.001 wt % to about 4 wt % metal nanowires, from about 0.05 wt % to about 5 wt % solid hydrophilic polymer binder soluble in the solvent, and from about 0.0001 to about 0.5 wt % metal ions provided to the ink as a dissolved fusing solution, having from about 5 wt % to about 60 wt % ethanol in the aqueous solvent.
A metal nanowire ink comprising an aqueous solvent, from about 0.001 wt % to about 4 wt % silver nanowires, from about 0.0001 to about 0.5 wt % metal ions provided to the ink as a dissolved fusing solution, anions selected from the group consisting of nitrates, sulfates, perchlorates, acetates, fluorides, chlorides, bromides, and iodides, and from about 10 wt % to about 60 wt % ethanol in the aqueous solvent at a pH from about 5.5 to about 7.5 pH units.
A metal nanowire ink comprising from about 0.001 wt % to about 4 wt % metal nanowires, from about 0.05 wt % to about 5 wt % hydrophilic polymer binder, from about 0.0001 to about 0.5 wt % metal ions provided to the ink as a dissolved fusing solution, and from about 5 wt % to about 60 wt % ethanol in an aqueous solvent, wherein the hydrophilic polymer binder comprises a polymeric polyol.
