On page 1450 (DOI: 10.1002/polb.24057 ) Zhida Wang, Fengman Sun, Shilin Huang, and Changfeng Yan synthesized toroidal, fiber‐like and rod‐like nanostructures of P4VP‐ b ‐PS‐ b ‐P4VP triblock copolymer micelles with temperature‐controlled reversible morphological changes. The toroidal micelles, evolving from fibers at 20 °C, can transform to fiber‐like or rod‐like micelles as the temperature increases to 60 or 80 °C, respectively. The transition mechanisms are quite different for diverse temperature changing methods due to the existences of various metastable states, indicating that the micellar morphologies depend on specific temperature, whereas the transition mechanism is relative to the process of temperature change.
