Temperature-responsive surface wettability of emulsion thin films by controlled Spinodal decomposition |
| 초록 |
We fabricate the emulsion thin film by utilizing the layer-by-layer (L-b-L) deposition. The nanoemulsion used in our study was fabricated through assembly of amphiphilic block copolymer and lecithin at the oil-water interface. The development of extremely stable charged nanoemulsions allowed us to employ L-b-L assembly by taking advantage of the electrostatic attraction. The thickness of the nanoemulsion films was tunable to few micrometer scales by solely changing the number of alternate emulsions and polyelectrolytes layers. It was remarkable that the nanoemulsion films had the thermally responsive Spinodal decomposition, thus enabling manipulation of surface wettability. These results highlight that a new type of controlled drug delivery can be developed based on the patch-type soft film cargos. |
