Fabrication of high-quality silver nanowire conductive film and its application for transparent film heaters

Here, we report a facile method to produce pure silver nanowires (AgNWs) with high yield. A highly conductive dispersant was used to ensure uniform dispersion of the AgNWs. Without any posttreatment, the AgNW networks, deposited on flexible substrates, showed excellent optoelectrical performance owing to minimal junction resistance between the AgNWs. To explore their potential in flexible optoelectronic devices, a transparent film heater was constructed based on the present AgNW networks. The heater could achieve rapid response at low input voltage and reach a relatively high temperature in a short response time. Since this high-quality AgNW film exhibits relatively low production costs and fast production time, it may have value for future electronic industry applications.
