Abstract
In this study, we report a simple alignment method to align silver nanowires (Ag NWs) using a dip-coating technique while controlling the temperature of glass substrate and Ag NW dispersion. It is found that the structural anisotropy and transmittance characteristics of the substrate lined with the Ag NWs depend on the temperature of the dispersion and substrate and the withdrawal velocity. The maximum structural anisotropy of the aligned Ag NWs was 0.947 at a withdrawal velocity of 1.0 mm/s and a temperature of 80 °C. In addition, a glass substrate with the aligned Ag NWs shows a high transmittance of 96.7% at the sheet resistance of 22 Ω/sq.
Highlights
The development of transparent electrodes had led to a wide range of applications, such as transparent displays, touch panels, and organic photovoltaics (OPVs), among others
Low resistance is an important factor in transparent electrodes, though transmittance is a very important factor
The evaporation rate of the dispersion can be controlled by the temperature of the glass substrate and Ag NW dispersion
Summary
The development of transparent electrodes had led to a wide range of applications, such as transparent displays, touch panels, and organic photovoltaics (OPVs), among others.
