Worm-like reversed micelles with a CO2-philic surfactant

Abstract: Hydrotropes (Figure 3 A-C) are known viscosifying agents with surfactants in organic solvents1 and interestingly now in supercritical CO2 (scCO2)5. The mechanism is hydrotrope-induced micelle growth to generate worm-like reverse micelles (WLRMs) 1,3,5. This experiment is to develop new surfactant+hydrotrope (or phenol) gelator combinations which are not only organophilic, but are also at same time CO2-philic. These would be unique WLRM systems, able to viscosify/gelate both oils and scCO2. In this initial phase organogelation will be studied, and these results will inform future studies with the same mixtures in scCO2 under high pressure conditions. A new approach taken here is to combine hydrotropes and phenols with a known CO2-phillic surfactant (TC14, Figure 2), and for these three-component mixtures greater viscosity enhancements are expected than for hydrotropes alone.
