Controlling the nanoscale interactions of colloidal building blocks is a key step for transition from single nanoparticles to tailor-made, architected morphologies and their further integration into functional materials. Solvent evaporation-induced self-assembly within emulsion droplets emerges as fast, versatile, low-cost approach obtain spherical, complex structures, such supraparticles. Nevertheless, some process–structure relationships able describe effects conditions on synthesis outcomes still remain be understood. Here, we explore effect different physicochemical parameters emulsion-templated (ETSA) supraparticles' formation. Supraparticle size, size dispersity, microporosity, sample homogeneity are rationalized based used surfactant formulation, stabilization mechanism, viscosity emulsion. We demonstrate significance found by optimizing transferable, large-scale (gram-size) ETSA setup controlled spherical supraparticles in range defined sizes (from 0.1–10 μm). Ultimately, our results provide new synthetic control process, promoting development supraparticle-based, nanomaterials wide applications.
