What is Novel Fixed-site–carrier Polyvinylamine Membrane for Carbon Dioxide Capture about?

## Abstract Fixed‐site–carrier membranes were prepared for the facilitated transport of CO~2~ by casting polyvinylamine (PVAm) on various supports, such as poly(ether sulfone) (PES), polyacrylonitrile (PAN), cellulose acetate (CA), and polysulfone (PSO). The cast PVAm on the support was crosslinked by various methods with glutaraldehyde, hydrochloric acid, sulfuric acid, and ammonium fluoride. Among the membranes tested, the PVAm cast on polysulfone and crosslinked by ammonium fluoride showed the highest selectivity of CO~2~ over CH~4~ (>1000). The permeance of CO~2~ was then measured to be 0.014 m^3^ (STP)/(m^2^ bar h) for a 20 μm thick membrane. The effect of the molecular weight of PVAm and feed pressure on the permeance was also investigated. The selectivity increased remarkably with increasing molecular weight and decreased slightly with increased pressure in the range of 1 to 4 bar. © 2004 Wiley Periodicals, Inc.
