Wettability and spontaneous penetration of a water drop into hydrophobic pores

[Display omitted] •A critical condition was found for a water drop penetrating into a surface with micro-pores.•This is due to the force balance.•Surface porosity and wettability are important factors affecting penetration. The penetration of a water drop into hydrophobic pores reflects its instabil...
