摘要: 本研究设计合成了一种具有温敏型开关特性、表面活性的共聚物(THFAA-NIPAM-PEGMA)，是一种可以仅通过改变温度就可以控制其乳化/破乳性质的新型表面活性剂。通过表面张力、界面张力以及乳化性能测试，表明了其具有良好的表面活性及乳化能力。通过表观温敏性、透光率曲线，以及不同温度下界面张力的比较，表明了其具有温度敏感特性，并阐述了温敏机理。通过乳化/破乳测试，表明了其具有温敏开关乳化/破乳特性。
Abstract: A surfactant copolymer (THFAA-NIPAM-PEGMA) with temperature-sensitive switching characte-ristics was designed and synthesized in the study. It is a new surfactant whose emulsification/ demulsification behavior can be controlled only by changing the environment temperature. The results of surface tension, interfacial tension, and emulsifying properties show that it has good surface activity. The apparent temperature sensitivity, transmittance curve, and the comparison of interfacial tension at different temperatures show that it has temperature sensitivity, and the mechanism behind is expounded.
