摘要

微凝胶是一种优秀的乳化剂,可以自组装以降低界面张力并在油水界面形成空间屏障。在此,我们报道了一种两步乳化方法,通过将微凝胶分散在两个不混溶相中来制备油包水包油(O/W/O)Pickering双乳液。稳定机制取决于亲水性水溶胀微凝胶和疏水性辛醇溶胀微凝胶在外部水滴或内部油滴上的不均匀分布和吸附。我们的结果表明,二元微凝胶在界面张力降低和乳液稳定性方面优于单元微凝胶。值得注意的是,由于微凝胶固有的热敏感性,二元微凝胶稳定的Pickering双乳液显示出优异的温度响应性。因此,可以通过调节环境温度来实现不同相中的包封物质的选择性和快速释放。

Temperature-Responsive Pickering Double Emulsions Stabilized by Binary Microgels

Microgels are excellent emulsifiers that can self-assemble to reduce interfacial tension and form a steric barrier at an oil-water interface. Herein, we report a two-step emulsification approach to prepare oil-in-water-in-oil (O/W/O) Pickering double emulsions through the dispersion of microgels in two immiscible phases. The stabilization mechanism depends on the uneven distribution and adsorption of hydrophilic water-swollen microgels and hydrophobic octanol-swollen microgels on either outer water droplets or inner oil droplets. Our results reveal that binary microgels outperformed single microgels in terms of interfacial tension reduction and emulsion stabilization. Notably, the binary microgel-stabilized Pickering double emulsions show excellent temperature responsiveness owing to the intrinsic thermal sensitivity of microgels. Consequently, the selective and rapid release of encapsulated substances in different phases can be achieved through the adjustment of the ambient temperature.

期刊介绍: Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
