We demonstrate that the traditional emulsification theory can be enriched by a self-assembly approach, in which hydrophilic copolymers with one block exhibiting noncovalent forces with the oil phase self-assemble at the oil–water interface, thereby reducing interfacial tension and forming emulsions. This approach was established using affinity diblock copolymers that can interact with oil molecules through electrostatic interactions or hydrogen-bonding. Nanoemulsions with excellent stability were successfully obtained simply via vortexing. The self-assembled emulsions showed unexpected catastrophic phase inversion, further extending the phase structures to bicontinuous and reverse emulsions. Complex emulsions could also be fabricated by this strategy. In addition, the thus prepared nanoemulsions can be used to engineer different nanomaterials.

通过非共价相互作用介导的界面自组装形成的高级乳液†

我们证明，传统的乳化理论可以通过一种自组装方法得以丰富，在该方法中，具有一嵌段的亲水共聚物在油水界面处自组装，并且油相自组装，从而降低了界面张力并形成了乳液。这种方法是使用可以通过静电相互作用或氢键与油分子相互作用的亲和性二嵌段共聚物建立的。简单地通过以下方法成功获得了具有优异稳定性的纳米乳液涡旋。自组装乳液显示出意外的灾难性相转化，进一步将相结构扩展到双连续和反向乳液。复杂的乳液也可以通过这种策略来制备。另外，如此制备的纳米乳液可用于工程化不同的纳米材料。
