Changing under pressure : Compressed CO 2 can switch the surfactant sodium bis‐2‐ethylhexylsulfosuccinate/water system between a lamellar liquid crystal (L α ) phase and a micellar solution (L 1 ) reversibly at ambient temperature. Applications of this simple, clean, and energy‐efficient process in material synthesis are explored, along with a possible mechanism for the phase‐transition phenomenon.
