제목 The first approach to fabricate multilayered smart emulsion films by layer-by-layer deposition
초록 We first successfully prepared thermally responsive multilayered nanoemulsion films consisting of charged nanoscale emulsion drops and polyelectrolytes by utilizing the layer-by-layer deposition technology. Basically, we used extremely stable nanoemulsions that fabricated through co-assembly of amphiphilic block copolymer and lecithin. These emulsions were specialized in offering both mechanically robust polymeric membrane and charged emulsion drops. The thickness of the nanoemulsion films was tunable in submicron scales by solely changing the number of alternate emulsions and polyelectrolytes layers. It was remarkable to experimentally figure out that the emulsion films had the thermally responsive heterogeneous phase separation, which could be understood by the spinodal decomposition. This intriguing behavior enabled the controlled release of active compounds from the emulsion films.
