  "abstract": "Control over the fabrication and morphology of supraparticles by processes such as spray drying is critical for designing materials for specific applications. We demonstrate morphological control to prepare either spherical or buckled supraparticles via evaporation-induced self-assembly of aqueous aerosol droplets containing two or more populations of sterically-stabilized diblock copolymer nanoparticles of varying size. Supraparticles are prepared at a relative humidity of either 0% or 45% when using monomodal, bimodal, trimodal, tetramodal, or pentamodal nanoparticle dispersions. The final supraparticle morphology is controlled by adjusting the relative concentrations of nanoparticles of differing size to tune the mean nanoparticle diffusion coefficient, which is inversely proportional to the harmonic mean of the nanoparticle diameter. This harmonic mean-based approximation enables the final supraparticle morphology to be accurately predicted by controlling the diffusion coefficient and evaporation rate. This approach is valid for systems with moderate size disparities. However, if the smallest nanoparticles are more than ten times smaller than the largest nanoparticles, then diffusion-driven segregation of the smallest nanoparticles at the surface of the drying aqueous droplets determines the final supraparticle morphology.",
