Abstract

A large variety of supracolloidal structures including biomimetic helices, low-coordinated two-dimensional (2D) and three-dimensional (3D) open lattices, and quasicrystal, have been achieved in experiments and simulations through the self-assembly of surface-anisotropic Janus and patchy particles. According to their different elastic moduli, surface-anisotropic Janus and patchy particles may be classified into two major categories: hard Janus and patchy particles, and soft Janus and patchy particles. This chapter introduces two major kinds of general and effective mesoscale models to describe the aggregation behavior of soft Janus and patchy particles: soft Janus particle models (SJPMs) and soft patchy particle models (SPPMs). SJPMs are specifically designed to study the aggregation behavior of soft one-patch, and ABA-type and BAB-type triblock Janus particles, and SPPMs are mainly developed to simulate the aggregation behavior of soft multi-patch particles with tunable number, size, direction, and geometrical arrangement of the patches.
