Spot-like Patchy Particles: Thermo-reversible Gelation, Phase Separation and Self-Assembly
I have considered models of patchy colloids consisting of hard sphere
particles decorated by a small number of identical short-ranged attractive
sites arranged in regular geometries on the particle surface. I have used
these simple models to numerically and theoretically explore phenomena such as
the formation of ideal gels or so-called empty liquids.
By combining the Wertheim theory for association and the Flory-Stockmayer
approach of chemical gelation, I have developed an analytical parameter-free
description for the equilibrium behavior of patchy systems, which I have also
validated via comparisons with extensive Monte Carlo simulations in various
ensembles, focusing on the region of the phase diagram where colloid
poor-colloid rich phase separation, network formation and clustering take place.
