Area of Science:

  • Surface Science
  • Interfacial Phenomena
  • Fluid Dynamics

Background:

  • Liquid droplet interaction with solid substrates is governed by surface tension and solid structure.
  • Previous studies have addressed these factors independently, limiting a comprehensive understanding.
  • A combined approach is needed to explore wetting and non-wetting regimes more deeply.

Purpose of the Study:

  • To investigate the coupled effects of liquid surface tension and micro-pillared surface structure on wetting regimes.
  • To understand droplet asymmetry and behavior across various liquid compositions and surface spacings.
  • To develop a wetting regime map for diverse liquid-solid interactions.

Main Methods:

  • Utilized intrinsically hydrophobic micro-pillared surfaces with varying structure spacing.
  • Employed pure ethanol, pure water, and their binary mixtures (including acetone-water and ethylene glycol-water).
  • Performed wettability measurements at different azimuthal directions to analyze droplet behavior.

Main Results:

  • High surface tension fluids (high water concentration) favor the Cassie-Baxter regime.
  • Low surface tension fluids (high ethanol concentration) exhibit Wenzel or mixed-mode regimes with enhanced droplet asymmetry below specific micropillar spacing.
  • Surface structure impact becomes negligible beyond 40 µm spacing, with droplets behaving similarly to those on flat surfaces.

Conclusions:

  • The interplay between liquid surface tension and surface structure spacing dictates wetting regimes and droplet asymmetry.
  • Classical wetting theories can explain the observed phenomena.
  • A comprehensive wetting regime map is proposed for various liquid-solid interactions.
