Polymeric membranes for CO2 capture

The object of this PhD work is the study of innovative, composite and nanostructured polymeric materials for membrane-based separation and removal of CO2 from gaseous streams. The research on gas separation membranes, in the last two decades was largely devoted to the synthesis and fabrication of...
