A one-step moderate energy vibrational emulsification method was successfully employed to produce thermo-responsive olive/silicone-based Janus emulsions stabilized by poly(,-diethylacrylamide) carrying 0.7 mol% oleoyl side chains. Completely engulfed emulsion droplets remained stable at room temperature and could be destabilized on demand upon heating to the transition temperature of the polymeric stabilizer. Time-dependent light micrographs demonstrate the temperature-induced breakdown of the Janus droplets, which opens new aspects of application, for instance in biocatalysis.
采用一步中能振动乳化法成功制备了由携带0.7 mol%油酰基侧链的聚（N，N-二乙基丙烯酰胺）稳定的热响应性橄榄/硅基Janus乳液。完全包裹的乳液滴在室温下保持稳定，加热至聚合物稳定剂的转变温度时可按需使其失稳。随时间变化的光学显微镜照片显示了Janus液滴的温度诱导分解，这为例如生物催化等新的应用领域开辟了道路。
