Dewetting of Water-Isopropanol Monolayers Between MoS₂ Membranes

Wetting and dewetting phenomena are important in the synthesis of layered materials by liquid-phase exfoliation. We perform molecular dynamics (MD) simulations to study dewetting of a monolayer of H₂O and H₂O-isopropanol (IPA) mixtures between two atomically thin MoS₂ membranes. Our simulations reveal rapid dewetting in which dry patches on MoS₂ move at a speed of 500 m/s with the solvent forming nanodroplets. The dynamic contact angles of solvent nanodroplets during dewetting are different from that of a standalone droplet on an MoS₂ surface. We also investigate dewetting of H₂O-IPA mixtures with different IPA concentrations. Results for the structure and dynamics of nanodroplets of water and H₂O-IPA mixtures after dewetting will be reported.
