Area of Science:

  • Surface Science and Engineering
  • Computational Fluid Dynamics
  • Materials Science

Background:

  • Understanding droplet behavior on patterned surfaces is crucial for applications like microfluidics and coatings.
  • Surface wettability patterns significantly influence droplet equilibrium shape and spreading dynamics.
  • Previous studies often focused on uniform surfaces or simple patterns, necessitating investigation into complex stripe geometries.

Purpose of the Study:

  • To investigate the equilibrium shape of droplets on surfaces with alternating hydrophobic and hydrophilic stripes.
  • To explore the relationship between stripe width ratio and droplet aspect ratio and contact angle.
  • To develop an analytical model for predicting droplet geometry on patterned surfaces.

Main Methods:

  • Utilized simulations employing the finite element method to model droplet behavior.
  • Conducted experimental investigations with two liquids of differing surface tensions.
  • Analyzed droplet aspect ratio and contact angles parallel to the stripes.

Main Results:

  • Droplet shape strongly elongates on surfaces with narrow hydrophobic stripes relative to hydrophilic ones.
  • Aspect ratio approaches unity with narrow hydrophilic stripes.
  • Unique scaling behavior observed for aspect ratio and parallel contact angle, dependent on stripe width ratio.

Conclusions:

  • Droplet geometry on striped surfaces is governed by equilibrium contact angles and stripe width ratio.
  • Simulations and experiments show consistent scaling laws.
  • A simple analytical expression accurately approximates the droplet aspect ratio.
