Block copolymer membrane at oil-water interface

본문

We have developed a technique to produce extremely stable oil-in-water nanoemulsions in which the interface is stabilized by assembly of amphiphilic poly(ethylene oxide)-block-poly-(ε-caprolactone) copolymers. The essence of our approach is to use phase inversion emulsification, induced by variation of the water volume fraction, thus facilitating effective assembly of the block copolymers at the oil-water interface. Kyounghee is working on this project. Like always her work is so wonderful!!!
