摘要： 就传统的乳液体系而言，用于实现分离、生产、研究应用目的之后，乳液破除操作存在诸如不能对乳化剂、破乳药剂回收循环复用及破乳成本高等问题。环境刺激响应型乳液体系是指能够对光、磁、pH、CO₂等信号刺激产生响应的新型智能乳状液体系。本文分别介绍了具有光、磁、pH、CO₂环境刺激响应性能乳液体系的相关研究成果及潜在的应用研究价值，一方面，相较传统的乳液体系，环境刺激响应型乳液体系对于实现乳状液破除、循环利用乳化剂、乳状液油相以及回收目标物提供了便利；另一方面，其也拓宽了乳化液用于催化、材料合成、药物运载与可控释放等领域的空间。最后，指出了环境刺激响应型乳液体系相关研究所存在的不足之处并对研究前景进行了展望。

Abstract: In practice, the conventional water-in-oil and oil-in-water emulsion systems are applied in the process of separation, production and research, after which demulsification is required. However, it is problematic, such as high cost, irrealizable recovery of emulsifiers and demulsifier agents, to demulsify the conventional emulsion systems. Environmental stimuli-responsive emulsion systems are a novel family of intelligent emulsion systems, which can respond to signals, such as light, magnetism, pH and CO₂. The research and potential applications on environmental stimuli-responsive emulsion systems with performance responding to light, magnetism, pH and CO₂ were reviewed respectively. On one hand, compared with the conventional emulsion systems, it is facile to achieve demulsification, cycling of emulsifiers and oil phase and to recovery target object. On the other hand, it also broadens the space for emulsions applied in catalysis, material synthesis, drug delivery and controlled release, and so on. In the end, the existing problems and the development prospect of environmental stimuli-responsive emulsion systems were forecasted.
