Comprehensive Synthesis Study of Well-Dispersed and Solution-Processed Metal Nanowires for Transparent Heaters

Figure 7

(a) On the left is a photo for a transparent heater based on AgNWs on glass substrate; on the right is a photo of a transparent heater based on CuNWs. (b) IR-image for an AgNW heater that is subjected to an electrical input power of 6 W, which corresponds to a power density of 0.34 W/cm². (c) Temperature response as a function of the power density for an AgNW- and a CuNW-based heater. The dashed line represents a linear fit to the experimental data. (d) Increase in resistance, which was normalized with respect to the resistance at ambient conditions, for increasing power densities. Long-term degradation tests for AgNW- and CuNW-based heaters. (g) SEM images recorded for the 1.36 Ω AgNW heater shown in (e). The inset shows a higher magnification SEM-image with silver sulfide nanoparticles.
