Abstract: A transparent structure comprising a transparent substrate, a transparent resistive heating element mounted on the substrate, metal traces forming electrodes arranged to be in electrical contact with the transparent heating element and positioned around boundaries of a heated region defining a circuit for electrical flow through the transparent resistive heating element, and a power source connected to the electrodes with the capability of delivering at least 1 volts to the electrodes wherein the transparent resistive heating element comprises a sparse metal conductive layer comprising nanowire segments of noble metal coated silver having a sheet resistance from about 1 Ohms/sq. to about 300 Ohms/sq and having an unpatterned area of at least about 0.25 cm2.

Abstract: Near ambient temperature processing has successfully resulted in highly conductive coatings formed from silver nanowires. The electrically conductive materials can have a high loading of silver and low resistivities. The highly conductive materials can be formed using aqueous inks with high loadings of silver nanowires with greater than 3 wt % metal that is primarily silver nanowires. Methods of preparing the high loading inks can comprise forming a good dispersion of the silver nanowires and removing solvent to concentrate the dispersions. A range of binders can be used including, for example, UV crosslinkable binders. Generally, the organic concentration of the highly conductive materials is no more than 25 wt %, although this can correspond to higher volume fractions of organics while still achieving good electrical conduction.

Abstract: Room temperature processing has successfully resulted in highly conductive coatings formed from silver nanowires with a cellulose binder. The conductive coatings can be formed with silver salts to fuse the silver nanowires into a unitary fused metal nanostructured network. Even without added silver salts, low sheet resistance values can be obtained. Room temperature processing can be effective over a range of transmittance values from highly transparent to modestly transparent to translucent to opaque. The ability to form the transparent coatings opens the processing to a wide range of substrates that are not processible with higher process temperatures.
