Surface-compartmentalized micellar nanostructures (Janus and patchy micelles) have gained increasing interest due to their unique properties opening highly relevant applications, e.g., as efficient particulate surfactants, compatibilizers in polymer blends, or templates for catalytically active nanoparticles. We present a facile method for the production of worm-like Janus micelles based on crystallization-driven self-assembly of a double-crystalline triblock terpolymer with a crystallizable polyethylene middle block and two highly incompatible corona blocks, polystyrene and poly(ethylene oxide). This approach enables the production of amphiphilic Janus micelles with excellent interfacial activity by a comparably simple heating and cooling protocol directly in solution.

通过结晶驱动自组装两亲性双晶三嵌段三元共聚物的 Janus 胶束

表面分隔的胶束纳米结构（Janus 和片状胶束）由于其独特的性质而引起了越来越多的关注，从而开辟了高度相关的应用，例如作为高效的颗粒表面活性剂、聚合物混合物中的增容剂或催化活性纳米颗粒的模板。我们提出了一种生产蠕虫状 Janus 胶束的简便方法，该方法基于双晶三嵌段三元共聚物与可结晶聚乙烯中间嵌段和两个高度不相容的电晕嵌段聚苯乙烯和聚（环氧乙烷）的结晶驱动自组装。这种方法能够通过直接在溶液中的相对简单的加热和冷却协议来生产具有优异界面活性的两亲性 Janus 胶束。
