Abstract

Driving amphiphilic block copolymers to self-assemble into asymmetric and equilibrium nanostructures remains a challenge. Here, we use the temperature-directed morphology transformation (TDMT) method to tailor the self-assembly of block copolymers into asymmetric nanoparticles with either a single (i.e., tadpole) or multi-arm geometry directly in water and at scale (>10 wt % of polymer). These nanostructures were close to or at their equilibrium morphology and not a transient kinetically trapped structure since they did not change with the addition of high amounts of plasticizer, could be freeze-dried and rehydrated without any structural rearrangement.
