Inverse patchy colloids with two and three patches. Analytical and numerical study.

摘要: We propose an analytical solution of the multi-density Ornstein-Zernike equation supplemented by associative Percus-Yevick closure relations specifically designed to describe equilibrium properties novel class patchy colloidal particles represented inverse colloids with arbitrary number patches. Using Baxter’s factorization method, we reduce problem one nonlinear algebraic for fraction non-bonded patch. present closed-form expressions structure (structure factor) and thermodynamic (internal energy) system in terms this (and parameters model). perform computer simulation studies compare theoretical predictions pair distribution function, internal energy, single double bonds formed system, two versions model, each three consider models formation blocked patch-patch repulsion without repulsion. In general very good agreement between results is observed.
