Anion Size-Dependent Carbon Dioxide Adsorption Capacity in High-Purity Diallyldimethylammonium-Based Poly(ionic liquid)s

KOkohei okuboSKShowa KitajimaHKHitoshi Kasai

Key Points

  • This research aims to explore how the size of anions affects the carbon dioxide adsorption capacity of poly(ionic liquid)s.
  • Investigated various sizes of anions in diallyldimethylammonium-based poly(ionic liquids)
  • Measured CO2 adsorption capacities under controlled conditions
  • Analyzed the relationship between anion size and adsorption efficiency
  • Larger anions demonstrated higher CO2 adsorption capacity compared to smaller anions
  • Optimal anion size identified that maximizes CO2 capture
  • Findings can guide the design of more effective CO2 adsorbents

Abstract

Poly(ionic liquid)s ( PIL s) are solid materials composed of cationic or anionic polymers combined with counter ions. PIL s are investigated and applied as CO 2 adsorbents because they possess both the high...
