Area of Science:

  • Materials Science
  • Surface Physics
  • Physical Chemistry

Background:

  • Understanding liquid droplet behavior on solid surfaces is crucial for various applications, including microfluidics and materials deposition.
  • Previous studies often lacked high-resolution 3D shape analysis of dynamic wetting processes.

Purpose of the Study:

  • To investigate the dynamic shape evolution of mercury droplets spreading on thin silver films.
  • To quantitatively characterize the three-dimensional shape and wetting behavior of liquid metal on a solid substrate.

Main Methods:

  • Utilized polarized microscopy with differential interference contrast (DIC) for high-resolution imaging.
  • Employed semi-quantitative optical path difference (OPD) measurements to reconstruct droplet shape.
  • Achieved high angular (1 degree) and temporal (0.04 s) resolution to capture dynamic changes.

Main Results:

  • Successfully constructed the 3D shape of wetting mercury droplets on silver films.
  • Observed that the droplet maintains a distinct spherical-cup shape throughout the entire wetting-reaction process.
  • Quantitative data on droplet shape evolution was obtained and compared with other wetting systems.

Conclusions:

  • The spherical-cup shape is a stable configuration for mercury droplets on silver films during wetting.
  • The employed DIC-OPD method provides a powerful tool for quantitative analysis of dynamic wetting phenomena.
  • Findings contribute to a deeper understanding of liquid metal-solid surface interactions and wetting dynamics.
