A reusable wet-transfer printing technique for manufacturing of flexible silver nanowire film-based electrodes.

To explore a simple and efficient way to fabricate thin film electrodes on flexible substrates is highly desired because of its high promising application in optoelectronics. Transfer printing technique plays a key role in the fabrication of flexible electrodes from conventional substrates to flexible substrates. Unfortunately, a simple, room temperature, environmental-friendly and reusable transfer printing technique still remains challenging. Here we demonstrated a novel water-based wet-transfer printing technique that is simple, room temperature, environmental-friendly and reusable by taking advantage of the adjustment of the intermolecular hydrogen bonding between thin film and substrates. This effective and practical transfer technique may provide an effective route to develop electronic flexible devices with high performance.
