Transparent conductive films based on Ag nanowires and alginate hydrogel

Abstract

In this study, we report that the high-performance transparent conductive films based on silver nanowires (AgNWs) can be fabricated in a single-step spin-coating process by simply introducing a biocompatible polymer (alginate, Alg) into an aqueous suspension of AgNWs. The presence of Alg in the aqueous suspension enables AgNWs to be deposited on the substrate at a higher density, and AgNWs are uniformly distributed on the substrate without aggregation. In addition, through the treatment process using CaCl₂ aqueous solution, the conductivity of the AgNWs films can be further improved and their adhesion to the substrate is also enhanced.
