Abstract
Molecular dynamics is employed to investigate the impact of nanodroplets on superhydrophobic surfaces decorated with nanoridges. It is concluded that the decorated nanoridges can significantly promote the bouncing performance of nanodroplets. Five distinct bounce modes are identified, and they determine the variation laws of contact time and bounce velocity of nanodroplets.
