Abstract:

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 60wt% 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. Gas testing of these membranes for carbon capture applications showed enhanced CO2 permeances up to 1830GPU, without a significant drop in CO2/N2 selectivity at 35°C and 350kPa, relative to a pure PEBAX® upper layer. The impacts of temperature and pressure on membrane performance were investigated for temperatures from 25°C to 55°C and pressures from 100kPa to 500kPa. Theoretical calculations indicated that in the absence of a gutter layer, the upper layer could achieve a CO2 permeance of over 3000GPU with a CO2/N2 selectivity of 22. These results represent a significant increase in gas permeances compared with previously published results for similar membranes.
