Thermodynamics of Supercritical Fluids and the Applications for Preparing Microemulsions |
| 초록 |
We studied the microemulsions in supercritical (SC) CO2, the effect of compressed CO2on the structures of reverse micelles in organic solvents, and the reverse micelles of copolymers induced by compressed CO2, and some of the related applications were also investigated. The results demonstrated that non-fluorous nonionic surfactants, Dynol-604, Ls-36, Ls-45, and Ls-54, are soluble in SC CO2. The phase behavior and UV-vis studies showed that the Dynol-604 and Ls-54 could form reverse micelles in SC CO2. The microemulsions could solubilize methyl orange (MO) and biomacromolecules, indicating the existence of polar micro-aqueous environments. The results of synchrotron radiation SAXS suggest that the radii of the Dynol-604 based and Ls-54 based reverse micelles are in the ranges of 73.8∥78.1 and 20.4~25.2, respectively. The Ag, ZnS, and CdS nanoparticles, and ZnS/CdS and ZnS/PAM composite nanoparticles synthesized in sodium bis(2-ethylhexyl) sulfosuccinate (AOT) reverse micelles were recovered by dissolving antisolvent CO2into the micellar solution. |
