In this Letter, we report the morphological transition of dry block copolymer vesicles into onion-like multilamellar micelles induced through heating. When the temperature is higher than the glass transition temperature of block copolymer, the vesicles can collapse, and finally form onion-like multilamellar micelles via micro phase separation. This phenomenon is observed in both A–B and A–B–A block copolymer vesicles, indicating that the technique used in this study can be an alternative method to synthesize multilamellar micelles.
