Area of Science:

  • Materials Science
  • Surface Chemistry
  • Nanotechnology

Background:

  • Superoleophobic surfaces repel low-surface-energy liquids, exhibiting high contact angles (>150 degrees).
  • Designing these surfaces requires understanding how etched silicon surface geometry influences liquid interactions (contact angle and hysteresis).

Purpose of the Study:

  • To create superoleophobic surfaces on Si(111) using liquid-based metal-assisted etching and silane treatments.
  • To investigate the impact of etched surface geometry and silane modification on oleophobicity and wetting states.

Main Methods:

  • Fabrication of superoleophobic surfaces on Si(111) via liquid-based metal-assisted etching.
  • Application of various silane treatments to modify surface properties.
  • Analysis of apparent contact angles and hysteresis for low-surface-energy liquids.

Main Results:

  • Etch conditions (time, concentration) critically determined the oleophobicity of Si(111) surfaces.
  • Silane treatments induced a transition from Cassie to Wenzel wetting states for low-surface-energy liquids.
  • A direct relationship was observed between the re-entrant angle of etched structures and the wetting state transition.

Conclusions:

  • The study successfully fabricated superoleophobic Si(111) surfaces.
  • Surface topography and chemical functionalization are key to controlling wetting behavior.
  • Understanding the re-entrant angle is crucial for designing surfaces with tunable oleophobicity.
