In recent years, the self-assembly of block copolymers in confining geometries (i.e. dispersed droplets/particles) has gained growing interest due to unique morphologies which are rarely observed in the bulk state. Since colloidal particles are characterized by a significantly high surface area to volume ratio, a crucial parameter that controls the morphology of block copolymer domains in such systems is the interfacial interaction between the respective blocks and the surrounding media. Here, we report that fine tuning this parameter by utilizing functional surfactants during nanoparticles preparation by the solvent evaporation method provides promising opportunities to create block copolymer colloids with non-conventional shapes and morphologies.
