Fabrication and stabilization of nanoscale emulsions by formation of thin polymer membrane at oil-water interface |
| 초록 |
This study introduces a robust approach for the fabrication of extremely stable oil-in-water nanoemulsions in which the interface is stabilized by assembly of amphiphilic poly(ethylene oxide)-block-poly(ε-caprolactone) (PEO-b-PCL) copolymers during phase inversion. The prepared nanoemulsions were surprisingly stable against drop coalescence and aggregation, as confirmed by analysis of changes in the droplet size after repeated freeze-thaw cycling and by monitoring the creaming kinetics under conditions of high ionic strength and density mismatch. The results highlight that good structural assembly of the PEO-b-PCL block copolymers at the oil-water interface generated a mechanically flexible but tough polymer film, thereby remarkably improving the emulsion stability. |
