An example case of selective morphology by simply varying pH and heating profile based on a diblock copolymer, i.e., poly(N-isopropylacrylamide) (PNIPAAM) and poly[2-(dimethylamino)ethyl acrylate] (PDMAEA) is reported. A variation of pH induces an aggregation of the block copolymers in either micelles or vesicles. In a subsequent step, temperature variation triggers the formation of vesicular structures. This demonstrates not only the temperature but also the heating rate that tunes the nanostructures from micelles to vesicles.
