Development of novel fluorinated additives for high performance CO2 separation thin-film composite membranes
Abstract(#br)A series of poly(ethylene glycol)- block -poly(pentafluoropropyl acrylate) diblock copolymers were synthesized by Reversible Addition Fragmentation Chain Transfer (RAFT) polymerization. These block copolymers were blended up to 60\u003cce:hsp sp=\"0.25\"/\u003ewt% with commercially available PEBAX ® 2533. The resulting polymer mixtures were successfully spin coated onto cross-linked polydimethylsiloxane (PDMS) gutter layers which in turn had been deposited onto a porous polyacrylonitrile (PAN) support, to form a thin film composite membrane.
