Micelles

Micelle formation is an intricate process that hinges on the properties of amphiphilic or amphipathic molecules and the conditions of the system in which they are found. Amphiphilic molecules, which have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts, play a critical role in this process.In aqueous environments, these molecules arrange themselves such that their hydrophilic heads are turned towards the water phase, while their hydrophobic tails are oriented away...

Background:

Amine-based microemulsions are prone to volatilization, posing environmental and efficiency challenges.
Ionic liquids offer tunable properties but their application in responsive systems requires further exploration.
Controlling microemulsion microstructure is key for applications in separation and delivery.

Purpose of the Study:

To design and synthesize CO2-responsive microemulsions utilizing a novel ionic liquid surfactant.
To investigate the ability of these microemulsions to reduce amine volatilization.
To explore the reversible microstructural transitions induced by CO2 and N2/heat.

Main Methods:

Synthesis of 1,1,3,3-tetramethylguanidine-oleic acid (TMG-OA) ionic liquid.
Characterization of TMG-OA properties using NMR, pH, thermogravimetry, and interfacial tension measurements.
Preparation and characterization of CO2-responsive microemulsions with varying isopropyl alcohol (IPA) content.

Main Results:

TMG-OA demonstrated excellent switchability, stability, and surface activity.
Microemulsion size increased with CO2 introduction and decreased with N2/heat for higher IPA content.
Phase separation and regeneration of microemulsions with different sizes were observed for lower IPA content upon CO2/N2 cycling.

Conclusions:

The developed TMG-OA ionic liquid is effective in creating CO2-responsive microemulsions.
These microemulsions offer a promising approach to mitigate amine volatilization.
Reversible microstructural changes are driven by the CO2-induced conversion between TMG-OA and oleic acid components.
