Abstract

Poly(vinyl alcohol) (PVA) is a degradable, biocompatible and nontoxic polymer. The PVA functional films are flexible and suitable for use as flexible optoelectronic films. The transparent Ag nanowire/PVA films have received more and more attention due to their flexibility and abrasion resistance, compared with traditional indium tin oxide (ITO) films. However, the water resistance and manufacturing problems of the hybrid PVA films hinder their application. Here, we propose a simple method for fabricating hybrid PVA films, which can overcome the manufacturing problems of complex shapes and water resistance problems. The obtained Ag nanowire/PVA film is water-resistant, transparent, flexible and conductive, which is converted from hybrid hydrogel and driven by viscosity. Broadly, through this strategy of spraying Ag nanowire/PVA hydrogel precursors, the hybrid PVA films can be fabricated on the surface of three-dimensional molds with complex shapes, which has the potential for use in three-dimensional optoelectronic devices.
