Self-assembly of patchy nano-sized building blocks is an efficient strategy for producing highly organized materials. Herein, we report the chaining of divalent silica nanoparticles with polystyrene patches dispersed in THF triggered by lowering the solvent quality. We study the influence of the patch-to-particle size ratio and show that the nature of the added nonsolvent, e.g. ethanol, water or salty water, and its volume fraction shall be carefully adjusted. We demonstrate that colloidal assembly initially obeys the kinetic model of step-growth polymerization and that beyond a certain length the chains have the possibility to cyclize. We also show that the length of the chains can be controlled by the addition of one-patch silica nanoparticles, which act as colloidal analogues of chain stoppers.< Réduire
