Reversible CO sub(2) capture with porous polymers using the humidity swing

Several polymeric materials were prepared for reversible CO sub(2) capture. These materials contain quaternary ammonium ions and hydroxide counter ions, including polymers grafted from carbon black, crosslinked porous polymers templated by ordered colloidal crystals, and high internal phase emulsion...

Description
Summary:Several polymeric materials were prepared for reversible CO sub(2) capture. These materials contain quaternary ammonium ions and hydroxide counter ions, including polymers grafted from carbon black, crosslinked porous polymers templated by ordered colloidal crystals, and high internal phase emulsion systems. The porous polymers displayed an order of magnitude improvement in the kinetics of the absorption and desorption processes and a significant improvement in the swing sizes compared to a commercially available material with similar functional groups. This work suggests a new direction for the design of porous polymeric materials for CO sub(2) air capture.
