Capillary-Induced Interactions between Janus Particles at Liquid-Fluid Interfaces

Abstract

In this talk, I will discuss the capillary-induced interactions between Janus particles adsorbed at flat oil-water interfaces. The interface deforms around the particles due to surface heterogeneity and/or shape anisotropy, thus giving rise to energetic capillary-induced interactions. I quantify these interactions through evaluation of capillary energy variation as a function of the aspect ratio, amphiphilicity, separation distance and bond angle between the particles. I also discuss the preferred alignment and assembly of these particles into 1D chains.
