Modeling the Effective Interactions Between Heterogeneously Charged Colloids to Design Responsive Self-assembled Materials

摘要: Heterogeneously charged colloids have recently emerged as promising building blocks for the self-assembly of target structures with specific properties at nano- and micro-scale level. Owing to competitive interplay between orientation-dependent attraction repulsion—induced by interactions like/oppositely areas on particle surface—these can indeed favor stabilization interest, being same time subject an easy control means external parameters, such pH salt concentration. Here we describe how derive a reliable simple coarse-grained description effective pair spherical units inhomogeneous surface charge distribution. Such framework allows target—using state-of-the-art computational techniques appropriately developed theoretical approaches—the design, assembly responsiveness engineered regions, thus providing indispensable tool rational materials fabrication.
