Architecting oil/water emulsion interfaces for dipole-dipole attraction-mediated interdrop percolation |
| 초록 |
We introduce a new approach to architect the oil/water interface of nanoemulsion drops, in which amphiphilic ABA triblock copolymers and lipid assemble to generate dipole-dipole interaction-mediated interdrop percolation. Nanoemulsions used in this study were stabilized by interfacial assembly of amphiphilic triblock copolymers and lecithin. The amphiphilic triblock copolymer was poly (ethylene oxide)-b-poly (ε-caprolactone)-b-poly (ethylene oxide) with different molecular weights. To confirm the interdrop attraction, dense emulsion suspension rheology studies were conducted. Addition of lecithin to polymeric membrane led to dipole-dipole interaction between methoxy-terminal group of PEO chain and phosphorylcholrine group of lecithin. We also found that thermos-responsive chain conformation of PEO at the interface was essential for controlling the interdrop percolation. These findings support the potential use of our attractive nanoemulsion system over a wide range. |
