摘要：
Poly(1,2-butadiene-block-ethylene oxide) (PB-PEO) block copolymer micelles are found to partition reversibly between an ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF6]) and water, thereby functioning as micellar shuttles controlled simply by temperature. The micelle size and structure are preserved during this reversible phase transfer. This phenomenon offers a simple means to transport chemicals back and forth between two immiscible phases.
