Although the synthesis of monodisperse polystyrene nanoparticles (MPSPs) in surfactant-free systems has been widely investigated, role mesostructures forming MPSPs is still unclear. Herein, styrene/ethanol-water (St/EtOH-H2O) ternary system with certain was employed as a model to investigate correlation between mesostructure and properties products. The system, including styrene droplets, sponge-like structure, water were investigated by transmission electron microscope (TEM) negative staining, dynamic light scattering (DLS), nanoparticle tracking analysis (NTA). Classical molecular dynamics (MD) simulations showed spontaneous aggregation ethanol at styrene-water interface, which may be one factors stabilizing mesostructures. We demonstrated that formation can only occur containing droplets. Cooling reactants droplet early stages polymerization resulted incomplete nanospheres (PSNSs), indicating originated from interface Subsequently, gradually formed through self-templating polymerization. This study offers valuable insights into preparation understanding process polymer other similar systems.
