Abstract

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.

摘要

聚（1,2 - 丁二烯 - 嵌段 - 环氧乙烷）（PB - PEO）嵌段共聚物胶束被发现可在离子液体1 - 丁基 - 3 - 甲基咪唑六氟磷酸盐（[BMIM][PF6]）和水之间可逆分配，从而起到仅由温度控制的胶束穿梭作用。在这种可逆相转移过程中，胶束的大小和结构得以保留。这一现象为在两个不混溶相之间来回运输化学物质提供了一种简单方法。
