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.
