Self-assembly in 2D competitive colloids

Abstract:
The study of chemical building blocks as amphiphilic molecules, block copolymers, colloids and nanoparticles have attracted the attention in soft matter physics in recent years due their properties of self-assembly. The variety of the length scales and geometry of the patterns arise from the different types of potential energies involved and from the shapes of the colloidal particles. Particullarly, spherical colloids with tunable competitive interactions can be used to generate distinct aggregated patterns. The combination of a short attractive interaction and a long range repulsion can describe the nucleation in these systems with competitive interactions. In this talk, I’ll discuss our recent findings in the behavior of these colloids in 2D and quasi-2D systems, as the relations between aggregation and diffusion.
