Design, synthesis and characterization of mixed matrix material for CO2 capture
Résumé
In the actual context of CO2 capture, attempts have been made to incorporate mineral fillers (zeolithe, active carbon, ...) in various types of polymeric matrix to enhance their separation performances [1]. One challenge of this approach is to synthesize defect free structures with high loading factor. We present in this study the synthesis and the sorption characterization of mixed matrix materials containing active carbon included in rubbery polymers. Active carbon fillers were selected because their adsorption capacity for CO2 is known to be very high compared to other fillers. One of the objectives of this work was to determine whether the affinity for CO2 of the carbon particles would be preserved in a polymeric matrix synthesised from PDMS oligomers.
