Stable oil-in-water emulsions formed with nanoparticles challenge existing theories. These findings reveal a new class of mesoscopic equilibrium structures, demonstrating thermodynamic stability in nanoparticle-stabilized emulsions.

Area of Science:

  • Colloid and Surface Science
  • Materials Science
  • Physical Chemistry

Background:

  • Pickering emulsions, stabilized by solid particles, are traditionally considered metastable.
  • Understanding the long-term stability and equilibrium behavior of nanoparticle-stabilized emulsions is crucial for various applications.

Purpose of the Study:

  • To investigate the thermodynamic stability of oil-in-water emulsions stabilized by nanoparticles.
  • To challenge the prevailing notion of metastability for Pickering emulsions.
  • To identify new mesoscopic equilibrium structures in colloidal systems.

Main Methods:

  • Forming oil-in-water emulsions using oil, water, and specific nanoparticles.
  • Analyzing droplet size distribution and its evolution over time.

Related Experiment Videos

  • Investigating the effect of salt concentration on emulsion properties.
  • Characterizing interfacial curvature and charge distribution.

    • Main Results:

    • Achieved thermodynamically stable oil-in-water emulsions with monodisperse droplet sizes (30-150 nm).
    • Demonstrated spontaneous evolution of binary droplet mixtures towards a single size distribution, indicating equilibrium.
    • Explained salt-induced droplet growth via equilibrium interfacial curvature from asymmetric colloid charge.
    • Observed a minimal radius of curvature analogous to microemulsions, with oil expulsion.

    Conclusions:

    • Nanoparticle-stabilized emulsions can exhibit true thermodynamic stability, forming equilibrium mesoscopic structures.
    • The findings necessitate a revision of current understanding regarding Pickering emulsion stability.
    • This work opens avenues for designing novel, stable emulsions with tunable properties.
