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

Figure 6

(a) Transmittance and haze spectra over the visible region for an increasing mass of sprayed AgNW ink. (b) R_S for different postdeposition treatments (see main text for more details). (c) Transmittance and haze at a wavelength of 550 nm for different R_S. The dashed lines serve as a guide to the eye. (d) ATR-FTIR spectra for an increasing mass of sprayed AgNWs before (dashed lines) and after (solid lines) immersion in H₂O. The inset indicates the relevant part of the PVP repeating unit and the C=O stretching mode that gives rise to the indicated absorbance peak around 1650 cm⁻¹. Carbon, hydrogen, oxygen, and nitrogen atoms are colored black, white, red, and blue, respectively.
