Molecular Insights into the Reversible Mechanisms of CO2-Switchable Surfactant Solubilization and Emulsification

stabilized emulsions by inserting hydrophobic chains into the dodecane oil droplet core and exposing hydrophilic headgroups at the interface, while DDA molecules mixed uniformly with the oil phase, triggering emulsion instability. The results align closely with experimental observation, verifying the reliability of the coarse-grained model in the simulation of complex multiphase systems. This work laid a methodological foundation for the molecular design and process optimization of switchable surfactants.
