Abstract

It was found that CO₂ could induce the gelation of Pluronic aqueous solutions, during which the microstructure of the solution transforms from randomly dispersed spherical micelles to cubic close packed micelles. The gelation switched by compressed CO₂ has many advantages and can be applied in the synthesis of porous materials.
