Abstract  

The present work deals with the interactions between carbon dioxide, used as pressure medium, either in the gas state (GCO2) or in the supercritical state (SCCO2) and amphiphilic di-block copolymers PEOm-b-PMA(Az)n. The effect of pressure on the isotropic transition of the PEOm-b-PMA(Az)n copolymer was investigated using scanning transitiometry (ST). The experimental results were compared with those measured when using ‘relatively inert’ mercury (Hg) as pressure medium. Morphological observation of a PEOm-b-PMA(Az)n thin film submitted to SCCO2 was performed by atomic force microscopy (AFM) to investigate the nano-structure organization. These results indicate the possibility of modifying the nano-structure in a specific way depending on the CO2 physical state.
