## Description

- description: Inspired by penguins, the formation of an air film on surfaces underwater
    has been well-researched for the potential reduction of drag. However, the features
    that contribute to drag reduction of penguins are not only the formation of an
    air layer but also the flow of bubbles along the air layer; basic investiga- tion
    of the wetting dynamics of a bubble scattered in an underwater environment has
    been overlooked. The focus of our research was microbubble contact on superhydrophobic/superhydrophilic
    surfaces underwater. Unlike the adhesion of mist in air, a “coalescence delay”
    is observed when bubbles make contact, which influences the deposition dynamics
    of an air film. The “coalescence delay” is propor- tional to the size of the bubbles.
    This study is helpful to understand air/solid/water systems as well as the drag
    reduction.
