제목 Structurally Stable Attractive Nanoscale Emulsions with Dipole-Dipole Interaction Driven Interdrop Percolation
초록 This study introduces an extremely stable attractive nanoscale emulsion fluid, in which the poly(ethylene oxide)-block-poly(ε-caprolactone) (PEO-b-PCL) is tightly packed with lecithin, thereby forming a mechanically robust thin-film at the oil-water interface. Our suspension rheology studies also reflect the interdroplet attractions over a wide volume fraction range of the dispersed oil phase; this results in a percolated network of stable drops. We have figured out that this unique rheological behavior is attributed to the dipolar interaction between the phosphorylcholine groups of lecithin and the methoxy end groups of PEO-b-PCL. Finally, we demonstrate that our nanoemulsion system significantly enhances transdermal delivery efficiency due to its favorable attraction to the skin as well as high diffusivity of the nanoscale emulsion drops.
