| Summary: | Molecular dynamics （MD） simulations are performed to explore the layering structure and liquid-liquid transition of liquid water confined between two graphene sheets with a varied distance at different pressures. Both the size of nanoslit and pressure could cause the layering and liquid-liquid transition of the confined water. With increase of pressure and the nanoslit＇s size, the confined water could have a more obvious layering. In addition, the neighboring water molecules firstly form chain structure, then will transform into square structure, and finally become triangle with increase of pressure. These results throw light on layering and liquid-liquid transition of water confined between two graphene sheets. |
