摘要

Here, we report a distinct mechanism for harnessing CO_(2)-responsiveness through enhancing CO_(2) capture ability. The finding is demonstrated on the microgels that are composed of oligo(ethylene glycol) and sulfonate moieties. Laser light scattering studies on dilute aqueous dispersion of these microgels indicated a low CO_(2)-responsivity, which can be significantly enhanced by adding NaCl and other salts. This salt-enhanced CO_(2)-responsiveness of microgels can be elucidated by the antipolyelectrolyte behavior and its superposition of forming cross-links physically with CO_(2) as an intermediate. Further results of the filtration experiments on microgel translocation through pores suggest the feasibility of the explanation. The finding is also supported by the CO_(2) capture-release experiments on the dispersion, which can reversibly absorb and desorb CO_(2).
