摘要

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.
