High-quality 2D films could be one-drop away

EurekAlert  May 19, 2023 The effective application of 2D materials is strongly dependent on the mass production of high-quality large area 2D thin films. Researchers in Japan demonstrated a strategy for the automated manufacturing of high-quality 2D thin films using a modified drop-casting approach. They used an automated pipette to drop a dilute aqueous suspension onto a substrate heated on a hotplate, and controlled convection. Liquid removal caused the nanosheets to come together to form a tile-like monolayer film in 1–2 min. Ti0.87O2 nanosheets were utilized as a model system for investigating the control parameters such as concentrations, suction speeds, […]
