Films containing poly(acrylic acid) (PAA) chains and polystyrene (PS) colloidal nanoparticles were analyzed using microbeam small-angle X-ray scattering (SAXS) and atomic force microscopy (AFM) to probe the impact of evaporation rates and colloid sizes on stratification behavior. Under slow drying conditions, particle-on-top stratification was observed, consistent with a diffusive model of stratification behavior. Conversely, moderate evaporation rates resulted in non-stratified configurations for certain mixtures. Fast evaporation, achieved by drying at elevated temperatures, induced polymer-on-top stratification, which aligns with predictions from simulations.
