Area of Science:

  • Materials Science
  • Colloid and Surface Chemistry
  • Polymer Science

Background:

  • Colloidal particles with specific surface patterns (patchy particles) are crucial for advanced materials.
  • Creating complex 3D patchy particles with controlled shapes and surface features remains a challenge.

Purpose of the Study:

  • To develop a simple and practical method for fabricating 3D colloidal patchy particles with tunable shapes.
  • To investigate the influence of interfacial interactions and polymer additives on particle morphology and patch characteristics.

Main Methods:

  • Evaporation-induced assembly of polystyrene-b-poly(4-vinylpyridine) (PS-b-P4VP) block copolymer (BCP) in an oil-in-water emulsion.
  • Modulation of interfacial interactions using a mixture of two surfactants.
  • Addition of P4VP homopolymers to control BCP stretching penalty and patch formation.

Main Results:

  • Successfully prepared various 3D patchy particle morphologies including snowmen, dumbbells, triangles, tetrahedra, and raspberry shapes.
  • Demonstrated precise control over particle shape and size by adjusting particle volume and interfacial tension.
  • Showed that adding P4VP homopolymers systematically tunes the number and size of patches by altering BCP stretching penalties.

Conclusions:

  • The developed method offers a versatile platform for creating complex 3D soft patchy particles.
  • Experimental observations are supported by strong segregation theory calculations, elucidating the formation principles.
  • This work provides a pathway for designing novel colloidal structures with tailored properties.
