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

Abstract

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.

Salt-Assisted Fabrication of a Water-Based Covalent Organic Framework Ink and Its Hybrid Films for Photothermal Actuators

“…This hybrid ink not only enhances the adhesion of TTA-COF to substrates but also improves the overall performance (Figures S20 and S21a). 37 Subsequently, the prepared ink was utilized to create a uniform hybrid TTA-COF film by employing the Mayer rod coating technique on a UV-ozone pretreated thin linear lowdensity polyethylene (LLDPE) layer, which was situated on an organic glass substrate (Figures S21b and S22). 38 Finally, the compact TTA-COF/LLDPE bimorph photothermal actuator was detached from the substrate and could be activated by near-infrared (NIR) light at 808 nm (see the detailed procedure in the Experimental Section).…”
