Two-step deposition of Ag nanowires/Zn2SnO4 transparent conductive films for antistatic coatings

Abstract

Silver nanowire (AgNW) networks play an important role in the transparent conductive electrodes or antistatic coatings. In this work, we describe a facile two-step method to fabricate AgNWs/Zn₂SnO₄ composite films. Long AgNWs with a high aspect ratio were prepared through a modified polyol method, in which the organic octylamine hydrochloride rather than the commonly used inorganic chlorides was used as the shape-controlling agent. The AgNW networks were fabricated on the glass substrate, on which the Zn₂SnO₄ film was deposited, forming robust AgNWs/Zn₂SnO₄ composite films. The as-prepared composite films have strong adhesion, high thermal stability, low sheet resistance (5–15 ohm sq⁻¹) and high light transmittance (85–80%), indicating a promising application prospect for transparent conductive electrodes and antistatic coatings.
