摘要
微乳液是由2种互不相溶的液体在表面活性剂(通常需添加助表面活性剂)作用下形成的均一透明、各向同性、热力学稳定的纳米液滴分散体系,在有机合成、纳米材料制备、药物运送、萃取分离等领域扮演着重要的角色。近年来,刺激响应型微乳液因其智能可控和潜在的绿色环保特征引起了广泛关注。CO_(2)刺激响应型微乳液是指在CO_(2)和N_(2)触发下可破乳/成乳的一类智能型微乳液。相对于传统的pH刺激,CO_(2)气体刺激不会带来污染(溶剂和副产物盐),且简单易得、绿色环保。从CO_(2)刺激响应型微乳的构筑出发,概括了表面活性剂基和无表面活性剂微乳液体系的最新研究进展,包括它们的相行为、结构、性质和潜在应用,并对其发展前景进行了展望。
Microemulsions are uniformly homogeneous and transparent,isotropic dispersions formed by two mutually immiscible liquids and surfactants(usually with the addition of co-surfactants).Microemulsions with small particle size and thermodynamic stability play an important role in the field of organic synthesis,nanomaterial synthesis,drug delivery,extraction separation and so on.CO_(2)/N_(2)stimuli-responsive microemulsion refers to a kind of smart microemulsion which can be demulsified/re-emulsified under the trigger of CO_(2)and N_(2).As CO_(2)gas is easy to get,green and environmentally friendly,and unlike the traditional pH response which will cause salt accumulation in the system,for which it has caused widespread interest.Based on the CO_(2)stimuli-responsive microemulsion,this paper summarizes the latest research progress of surfactant-based and surfactant-free microemulsion systems,including their phase behavior,structures,properties and potential applications,and prospects its development future.
