超临界二氧化碳微乳液的研究进展

Research progress of the microemulsions in supercritical carbon dioxide

系统地阐述了超临界二氧化碳微乳液的形成机理和概念,讨论了能形成超临界二氧化碳微乳液的表面活性剂和助表面活性剂的结构设计和选择。介绍了傅立叶红外光谱(FTIR)、电子顺磁共振(EPR)、核磁共振(NMR)、紫外可见光谱(UV-VIS)、X射线小角散射(SAXA)、中子小角散射(SANS)和动态光散射(DLS)等近代测试方法在超临界二氧化碳微乳液结构特性研究中的应用,并对超临界二氧化碳微乳液的研究应用进行了展望。

The principles and concepts of forming microemulsion in supercritical carbon dioxide were interpreted. The select and design of surfactants and co-surfactants were discussed. Some modem methods used to study the structural characteristics of microemulsions in supereritical carbon dioxide were introduced, such as the Fourier transform infrared spectroscopy （FTIR）, electron paramagnetic resonance （EPR）, nuclear magnetic resonance （NMR）, UV-vis spectra （UV-VIS）, small-angle X-ray scattering （SAXA）, small angle neutron scattering （SANS） and dynamic light scattering（DLS） and so on. The prospect of microemulsions in supercritical carbon dioxide was proposed.
