Assembly Of Polymer Colloids At Fluid Interfaces Through External Fields And Nanoscale Surface Topography, Samuel Trevenen

Doctoral Dissertations

The superposition of dipolar repulsion and capillary attraction energies between colloidal particles pinned at fluid interfaces dictates their microstructural organization and therefore the macroscopic interfacial material properties of particle-stabilized emulsions and 2D monolayer materials. While isotropic, spherical, particles have been extensively utilized, expanding the possible applications and material property tunability via anisotropic particles has been a challenge due to the propensity of particles to form disordered aggregates at the interface. My thesis presents the synthesis of anisotropic polymer ellipsoids and the development and use of experimental tools to study their interfacial behavior to reveal how dipolar and capillary interactions can …
